What Are the Different Functions of Each Hydraulic Pressure Level
by Emmanuel Emmanuel

What Are the Different Functions of Each Hydraulic Pressure Level?

Hydraulic pressure is a crucial source for manufacturers to create pressure consistently across a closed system, but it’s necessary to understand the diverse uses for different pressure ranges. Hydraulic systems may be employed at low pressures in the tens and hundreds of psi all the way up to 50,000 psi! With this in mind, it is critical to understand which range of hydraulic pressure controller is most effective for device calibration. understanding the functioning environment of the pressure gauge, transducer, or transmitter is just as important as understanding the pressure ranges. This may aid in determining the optimum hydraulic fluid for your procedure. The CPC8000-H Hydraulic Pressure Controller produces hydraulic pressure and works with a variety of media, the most popular of which being water and Sebacate oil.

Lower Levels

There are several applications that employ hydraulic pressure yet only require a few thousand psi to function. The CPC8000-H Low Pressure variant is appropriate for systems with a maximum pressure of 10,000 psi or less. This gadget can create pressure ranging from 75 psi to 10,000 psi with an accuracy of 0.008% of the reading.

Hydraulic systems are widely used in the automobile industry, from braking systems in ordinary vehicles to earth moving systems in tractors. Because the pressure measuring or fluid transporting components in these systems are generally less than 10,000 psi, they may be tested and calibrated using the LP version.

Image Source: mensor

Higher Levels

Sometimes going large is necessary to achieve your aim. The CPC8000-H’s high pressure (HP) variant can create pressures ranging from 290 psi to 58,000 psi, however it is still regarded considerably safer than pneumatic systems. If you’re not in an area that demands high pressure systems, it’s difficult to see why anybody would need that much pressure, yet many applications in the aerospace, automobile, and oil refinery sectors do.

Pressures in diesel engine combustion tests can exceed 20,000 psi. Hydraulic calibrators are frequently employed in these applications to assess the accuracy of measuring equipment. To improve the refining process, the oil and gas sector relies on precise, high pressure gauge or transmitter readings. High pressure sensing equipment is frequently used in aerospace testing to safely test fuel systems before they are employed on multimillion dollar equipment. The use of very precise hydraulic controllers allows them to have confidence that their system can withstand excessive pressures prior to installation.

Pressure Gauge Calibration - Gulf Coast Calibration
by Emmanuel Emmanuel

Pressure Gauge Calibration

Pressure gauge calibration is the process of comparing a pressure gauge’s accuracy to a recognized standard. This is accomplished by comparing the gauge’s output to that of a reference gauge or by delivering a known pressure to the gauge and measuring the output. Calibration may be done on a number of pressure gauges, including analog and digital gauges, and is a vital step in ensuring that the gauge provides accurate and trustworthy readings. Calibration of a pressure gauge often entails changing the gauge to ensure compliance with industry standards and regulations. To discover more about how pressure gauges operate, see our page on how they function.

How to calibrate a pressure gauge

Pressure calibration equipment such as a deadweight tester, standard pneumatic calibrator, or any other pressure gauge calibrator with an accurate reading is used to calibrate a pressure gauge. The main ideas and processes to calibrate a pressure gauge are quite same regardless of the tool, whether it’s mechanical or digital gauge calibration.

  • Using the proper adapter or fitting, connect the hand pump calibrator to the pressure gauge to be calibrated.
  • Set the hand pump calibrator to the required pressure.
  • Pump the hand pump calibrator gradually until the appropriate pressure is obtained.
  • Examine the pressure gauge and make sure it reads the same as the manual pump calibrator.
  • If the gauge does not read the right pressure, follow the manufacturer’s instructions.
  • Repeat the procedure at each pressure point to check that the gauge is accurate throughout its range.
  • Record the calibration results and make any required modifications.
    When the calibration is finished, remove the hand pump calibrator and store it properly.

Factors to consider for pressure gauge calibration

A precise pressure system is used for pressure calibration. The pressure reading on calibrated pressure gauges is logged and compared to the uncalibrated gauge to determine the margin of error. However, several factors can influence the calibration process and should be considered:

  • Accuracy class:

    The accuracy class is the pressure gauge’s maximum margin of error for the maximum scale reading. The accuracy class will assist operators in determining the permissible margin of error during calibration. The table below will assist you in determining the allowable error margin based on the accuracy class of the pressure gauge.

  • Pressure media:

    When calibrating a pressure gauge, it is best to utilize the same media that the pressure gauge is attached to. If this is not feasible, calibration with air/gas is appropriate for low-pressure gauges, whereas liquids are safer for high-pressure gauges.

  • Height difference:

    Because of the hydrostatic pressure of the medium, the difference in height between the pressure gauge calibration equipment and the pressure gauge might produce an inaccuracy during calibration. This is more common in liquid medium than in gas media. The size of the inaccuracy varies with the density of the liquid and the variation in height. If the calibration equipment and gauge cannot be placed at the same height, the effect of the height difference should be considered during calibration. A 2.5 cm (1 in) height variation allows for a pressure measurement error of around 0.02 bar (0.3 psi).

  • Contamination:

    Contamination such as dirt, moisture, or oil can harm both the pressure gauge and the calibration equipment. As a result, it is critical to ensure that the media and equipment are free of contamination and do not interfere with the operation.

  • Leak testing:

    A leak test is required prior to calibration because any leakage in the pipe system might cause calibration problems. Pressurizing the system, allowing the pressure gauge to settle, and monitoring the pressure are all ways to do a leak test. Any decrease in pressure might indicate a leak. During calibration, the pressure loss must be kept to a minimum.

  • Adiabatic effect:

    When the pressure quickly varies, the adiabatic effect can impair pressure gauge calibration accuracy. As the pressure fluctuates quickly, the temperature of the fluid inside the gauge changes, affecting the density of the fluid and hence the pressure. This might result in mistakes in the gauge’s reading, leading to erroneous calibration findings.

    It is advised to utilize a pressure gauge with a high-frequency response to reduce the impacts of the adiabatic effect during calibration. Such gauges have a quicker reaction time and can correctly monitor rapid pressure changes.

  • Pressurizing or exercising the gauge:

    Friction is caused by movement in mechanical pressure gauges. Exercising or pressurizing the system prior to calibration might help to minimize friction. This is accomplished by applying the nominal pressure, holding it for a minute, and then releasing it. Repeat two or three times more.

  • Mounting position:

    Because the pressure gauge is mechanical, the location of the gauge might impact the pressure measurement in the system. As a result, it is advised that the gauge be calibrated in the same place that it will be used in the real pressure measurement process. To guarantee proper installation, see the manufacturer’s instructions.

  • Readability:

    During calibration, adjust the input pressure so that the indicator needle always lands on a major scale mark instead of in between them. This makes the calibration process more convenient.

  • Hysteresis:

    The discrepancy in pressure readings when a gauge is subjected to increased and lowering pressure is referred to as hysteresis in pressure gauge calibration. In other words, it is the difference in pressure readings between when a gauge is calibrated while rising pressure and when it is calibrated while reducing pressure. Mechanical wear, temperature variations, and gauge design can all contribute to this variance. When calibrating pressure gauges, it is critical to account for hysteresis to guarantee accurate results.

  • Repeatability:

    Repeatability, or the ability to generate the same reading for the same input, is one of the characteristics of an accurate pressure gauge. Calibration is required if the gauge produces different results each time. It is advised that the gauge be pressurized for three cycles before calibration.

  • Environmental condition:

    The gauge reading may change depending on the temperature to which the procedure is subjected. Because the pressure gauge is typically calibrated at normal room temperature, changes in temperature can affect the accuracy of the pressure measurement. When calibrating, it is therefore advised to record the temperature and humidity.

  • Metrological traceability:

    Metrological traceability is critical in pressure gauge calibration because it assures that the gauge’s pressure measurements are accurate and compatible with the international system of units (SI). To establish metrological traceability in pressure gauge calibration, the gauge must be calibrated against a SI-traceable reference. The gauge is frequently compared to a recognized standard, such as a deadweight tester or a main pressure standard.

  • Calibration uncertainty:

    Calibration uncertainty might suggest a probable discrepancy in the calibrated value. Environmental factors, reference equipment, or operators taking the reading can all contribute to this uncertainty. It is critical to understand calibration uncertainty and separate mistake from uncertainty. Calculators for TUR (Test Uncertainty Ratio) or TAR (Test Accuracy Ratio) are one approach to be aware of linked uncertainty, albeit not all connected uncertainties are addressed. As a result, calculating the overall uncertainty of the calibration is advised to determine how successful the calibration is.

  • Calibration intervals:

    Pressure gauges must be calibrated on a regular basis to ensure the accuracy of the measurement. However, calibration requirements may vary based on the gauge’s purpose and design. Although there is no definitive answer, a typical guideline is once a year. However, it is also vital to verify for the manufacturer’s advise on the calibration time. Pressure gauges used in difficult working circumstances may necessitate more regular calibration.

In-house vs outsourcing calibration

Pressure gauge calibration can be done in-house or outsourced for maximum efficiency. The optimum option may be determined by the resources that a corporation is prepared to invest.

In-house calibration necessitates an investment in calibration equipment, specialists, training, and the establishment of a controlled environment. Even with these measures, it is difficult to establish verification of calibration accuracy. This is due to the fact that gauges and calibration equipment must continuously fulfill all of the stringent national and international criteria in order to validate the calibration process, which can be difficult for small in-house operations. These are some examples:

  • ISO/IEC 17025: This standard enables labs to demonstrate that they operate effectively and deliver legitimate findings, encouraging trust in their work both locally and globally.
  • ASME B40 – 2013: This American Association of Mechanical Engineers standard includes specifications for pressure gauges, components, diaphragm seals, digital pressure gauges, and more. The handbook covers vocabulary and definitions, dimensions, safety, construction, and installation difficulties, testing and calibration processes, and general suggestions.

The Difference Between NIST Traceable Calibrations and ISO-IEC 17025 Accredited Calibrations.
by Emmanuel Emmanuel

The Difference Between NIST Traceable Calibrations and ISO/IEC 17025 Accredited Calibrations.

Customers frequently inquire about the distinction between traceable and certified calibrations when attempting to identify what their goods require. Knowing the significance of each can assist in ensuring that all calibration requirements are completed.

A NIST traceable calibration is one in which a manufacturer or calibration laboratory certifies that the standards used to calibrate a product or device are traceable to the International System of Units (SI) via an unbroken chain of comparable measurements to the National Institute of Standards and Technology (NIST), a U.S. Department of Commerce agency. A broader description of traceability recognizes that metrological traceability to SI may be achieved through any accredited national metrology institution, not just NIST. This sort of calibration does not reflect or determine the degree of expertise of the calibration crew or laboratory. It primarily indicates that the calibration standard is traceable to NIST or another recognized metrology institution (RMI).

 

An ISO/IEC 17025 approved calibration is globally recognized. The ISO 17025 accreditation certifies the calibration laboratory’s competency. According to ISO 17025, any number of national metrology institutions, such as the NIST, must be internationally approved for acceptable measurement traceability. A third-party organization, such as A2LA, NAVLAP, or any number of other ILAC-MRA signatory organizations, is one way to show metrological traceability. These organizations evaluate the laboratory and its operations in order to determine the laboratory’s competence to perform calibrations and provide accredited calibration results. The certificate is linked with the scope of work for which the laboratory has been accredited. The laboratory is audited on a regular basis to verify that it is still in accordance with the ISO/IEC 17025 standard.

 

Because the discipline of calibration is assessed in addition to the traceability of the standards, ISO/IEC 17025 approved calibration may be regarded a step above NIST calibration. Furthermore, the ISO/IEC 17025 calibration comprises not only the measurement traceability, but also the measurement uncertainties of the calibration findings.

What is the difference between NIST traceable (or comparable) calibration and ISO/IEC 17025 calibration?

The decision is frequently made by a company’s quality manual or the quality department. The selection might also be influenced by how the equipment requiring frequent calibration will be utilized. For example, if the equipment is utilized in a vital application and the firm faces responsibility if something goes wrong, ISO/IEC 17025 calibration may be worth considering. If the device is used primarily for reference purposes in a low-risk environment where the measurement must be “close enough,” a NIST traceable calibration is most likely all that is necessary.

Critical measurements include altimeters in airplanes, nuclear plant temperature, flow measurements in which flow or volume is connected with a monetary value, and medical equipment that monitors air pressure.

Tire gauges, process gauges that indicate good or bad (usually with green and red areas on the dial face), pressure switches and pressure dial gauges used in air compressors, or torque wrenches used in auto repair shops are examples of non-critical, low risk measurement devices that may be suitable for NIST calibration.

It is ultimately the duty of the device’s owner to decide the proper form of calibration necessary – NIST or ISO/IEC 17025 approved – to guarantee the calibration fulfills the criteria of their industry.

More information about the ISO/IEC 17025 standard may be obtained on the International Organization for Standardization (ISO) website and the International Laboratory Accreditation Cooperation (ILAC) website.

External Factors and Corrections in Pressure Calibration
by Emmanuel Emmanuel

External Factors and Corrections in Pressure Calibration

Pressure calibrations entail more than simply recording the pressure number and comparing it to a recognized standard. Because pressure measurements are affected by several factors such as temperature, local gravity, pressure medium characteristics, and local adjustments, it is critical to account for these external factors and corrections when performing high precision pressure calibrations.

There is a wide range of calibration software on the market that automatically adds these corrections to the recorded pressure values from the reference and DUT. However, understanding the sources of deviation and errors in the calibration setup can be aided by being aware of these adjustments.

Site specific adjustments

Specific modifications are made to the recorded value to account for characteristics that impact the pressure output in respect to the location of the site and the ambient environment. These modifications may include sea level adjustments, local gravity adjustments, and temperature variations in the surroundings.

Typically, sea level adjustments are done to account for variations in height and barometric pressure. To compensate for gravitational forces on masses, local gravity corrections are utilized. Temperature compensation is used to capture the correct reference device output as the ambient temperature changes.

  • Sea Level

This adjustment is critical for absolute ranges, especially barometric pressure ranges. Regardless of height, this adjustment gives a common barometric reference. Because all of the barometers are calibrated to sea level, this makes it easy for meteorologists to track weather fronts.

As the altitude of an absolute sensor increases, it approaches absolute zero. However, this might cause issues with a barometric range sensor because the reading will no longer be 14.5 psi when vented to atmosphere. The local barometric pressure may instead be 12.0 psi. This is not the case when a sea level adjustment is applied. The present barometric pressure in Denver, Colorado, for example, will be closer to 14.5 psi than 12.0 psi. This is due to the sea level adjustment done to the barometer sensor.

  • Local Gravity

A correction for local gravity is the final site-specific adjustment and perhaps the biggest contribution to inaccuracies, particularly in piston-gauge systems. Gravity is the acceleration that allows mass sets to exert force on the piston area, resulting in pressure. The gravity of the Earth varies over its whole surface, with the lowest gravity acceleration being around 9.7639 m/s2 and the maximum gravity acceleration being roughly 9.8337 m/s2.

The local gravity may be used during the pressure calculation for a piston gauge, and a gravity adjustment may not be required. Many industrial deadweight tests, on the other hand, are calibrated to standard gravity (9.80665 m/s2) and must be rectified.

  • Temperature

Temperature fluctuations are another source of mistake in pressure calibrations. While pressure transducers, such as the CPT9000 Premium Pressure Transducer, are temperature adjusted during production, not all transducers are. Manufacturers of such transducers establish the connection of the pressure output’s accuracy to temperature rise or drop through applicable temperature standards.

Temperature adjustment is especially necessary for reference standards requiring temperature monitoring, such as piston gauges. Piston-cylinder systems, regardless of composition (steel, tungsten carbide, etc.), must be temperature corrected during operation since all materials expand or contract in response to temperature changes based on their thermal expansion coefficient.

As the temperature of the piston cylinder rises, the piston-cylinder system expands, increasing the area and decreasing the pressure generated. As the temperature drops, the piston-cylinder system contracts, causing the area to shrink. As a result, the pressure created rises. This modification will be delivered immediately to the piston’s region.

Media related adjustments

Media-related changes may be irrelevant to regular users of pressure controllers or gauges. However, media-related changes are required for primary standards since they affect the desired target specification and associated uncertainty.

  • Air Buoyancy

Air buoyancy is one of the most critical modifications that must be made to piston-cylinder systems.

The pressure generated by the air surrounding us acts as a column of air. It also exerts an upward pull on things at the same time. If this modification is not made, the displayed value may be incorrect. Any mass, including the piston, will require what is known as an air buoyancy adjustment.

This adjustment is only required for gauge calibrations in which the reference is exposed to ambient air (atmospheric reference). It is insignificant for absolute since the ambient air is effectively eliminated by using vacuum as a reference.

  • Surface Tension

When using oil-lubricated piston-cylinder systems, the surface tension of the fluid must be overcome in order to “free” the piston. Essentially, depending on the diameter of the piston, this results in an extra “phantom” mass load. As the piston’s diameter rises, so does the effect.

This adjustment is more critical at lower pressures and becomes less relevant as pressure increases.

Device specific adjustments

Device-specific modifications, such as head height and distortion correction (piston-cylinders only), are required for precision devices where slight changes in measurement might contribute to inaccuracies that effect the calibration’s total uncertainty.

  • Distortion

A distortion adjustment is a comparable correction that must be performed to piston-cylinder systems. As the pressure on the piston-cylinder system grows, the piston area increases, forcing it to create less pressure.

As the pressure grows, the piston area expands, resulting in less pressure than intended. The distortion coefficient is normally supplied by the manufacturer, although it may also be measured experimentally.

  • Head Height

If the reference standard is a pressure controller, the only correction that may be required is a head height correction. This adjustment cancels out the discrepancies in height / placement of the sensing elements in the reference relative to the DUT. If the DUT is below the reference level, the value will be positive; if the DUT is above the reference level, the value will be negative. A head height correction must be determined regardless of the pressure medium and dependent on the precision and resolution of the DUT.

Mensor pressure controllers, such as the CPC6050, Modular Pressure Controller, allow the operator to enter a head height and the instrument will compute the corrective head height.

Conclusion

Being aware of and compensating for the elements that influence the output of your pressure calibration may make a substantial difference in the total uncertainty of a calibration. While some of these adjustments, such as local gravity and sea level, will remain constant between calibrations, others will change dramatically depending on the reference device, pressure range, and even the equipment under test.
