- 2. 2 APPLICATION SELECTION GUIDE INTRODUCTION Process pressure devices provide critical process measurement information to process plant’s control systems. The performance of process pressure instruments are often critical to optimizing operation of the plant or proper functioning of the plant’s safety systems. Process pressure instruments are often installed in harsh operating environments causing their performance to shift or change over time. To keep these devices operating within expected limits requires periodic verification, maintenance and calibration. There is no one size fits all pressure test tool that meets the requirements of all users performing pressure instrument maintenance. This brochure illustrates a number of methods and differentiated tools for calibrating and testing the most common process pressure instruments.

- 4. 4 Suggested test tools Calibrating a HART Smart Pressure Transmitter Pressure transmitter manufacturers have improved the accuracy and technology designed into these smart pressure measurement devices. Many conventional calibration tools have become inad- equate or simply unable to test and calibrate these high accuracy pressure transmitters. Better test solutions are required. Verifying and documenting the performance and adjusting a HART smart pressure transmitter can require a bucket full of tools. Performing this task with a HART enabled calibrator like the Fluke 754 simplifies the task and reduces what you need to carry. Before going to the field: install the pressure module adapter to the hand pump with thread seal. Once the adapter is properly installed on the pump, changing modules to different pressure ranges is a snap, no tools required. To get the accuracy needed: to test these new high accuracy transmitters match the pressure measurement standard range closely to the device tested. For example, use a 100 psi pressure module to calibrate and test a transmitter ranged at 100 psi. Industry standards suggest the measurement standard should be 4-10 times more accurate than the device being tested so best-in-class accuracy is required. The Fluke 754 utilizes the 750P series pressure modules and has built-in HART functionality to enable smart trims on trans- mitters. It can also document transmitter performance before and after adjustment and calculate pass/fail errors.

Hand Pump Pressure Input mA Measure, 24V Loop Pressure Module 754 DOCUMENTING PROCESS CALIBRATOR + – – TEST PWR/ COMM 5 Sometimes it is necessary to trim the input sensor of the transmit- ter more than once. It is critical that the pressure module be ze- roed before test and adjustment. For best ßadjustment success: • After pressing Fetch for the pressure measurement, select the trim button quickly before the pressure measure- ment changes. • Give the measured mA and pressure time to settle for best measurement results. • Always de-bug the pressure test setup for leaks in the shop before going to the field, including installing the pressure module connection adapter to the hand pump. • If the full scale value of the transmitter is less than 25 % of the full scale of the pres- sure module, select a lower range pressure module for best results. • If performing higher pressure calibrations with a hydraulic pump, use the cor- rect fluid such as mineral oil or de-ionized water. Standard tap water will leave deposits in the pump and cause erratic operation, leaks or difficulty priming. • If the pass/fail accuracy is set at the limits for the transmit- ter, adjust the transmitter if the errors are greater than 25 % of limits. • If the errors are less than 25 % of limits, it might be best to not adjust the transmitter as adjusting might make it less accurate. Isolate the transmitter from the process being measured and its loop wiring. If measuring the mA signal across the transmitter test diode leave the wires intact, but note this method does not give the best mA measurement accuracy. Connect the mA measurement jacks of the 754 to the transmitter. Connect the pressure module cable to the 754 and connect the transmitter test hose from the hand pump to the transmitter. Press the HART button on the calibrator to see the configuration of the transmitter. Press HART again and the calibrator will offer the correct measure/source combination for the test. If documenting the calibration press As-Found, input the test tolerance and follow the prompts. If the measured mA signal at the test points is found within tolerance the test is complete. If not, adjustment is required. Select adjust and trim the transmitter’s pressure zero, mA output signal and input sensor. After adjustment select As-Left, document the condition of the transmitter after adjustment and if the test passes, it is complete.

They ensure that all components are in good working order prior to installation, and can evaluate them when component failure is suspected.

- 8. 8 Suggested test tools Pressure switch testing– manual approach Accurate calibration of pressure switches is a critical step in ensuring process quality and the safe operation of equipment. The setup is similar to pressure gauge calibration except now a voltage or continuity across a set of switch contacts needs to be read either by a (Digital Multimeter) DMM or the calibrator. The purpose of the calibration is to detect and correct errors in the set point and deadband of the pressure switch. Calibrators can save you time by reducing steps and reducing the amount of equipment you have to bring to the job. With the right calibrator the entire process can be automated.

The display will make it apparent that the set/reset has changed and the actuals will be logged. Safely disconnect the device from the process it controls. Connect the calibrator or DMM to the common and NO (normally open) output terminals of the switch. The DMM or calibrator will measure an “open circuit”. if measuring continuity. If measuring V ac be sure the tool is properly rated for the voltage being measured. Connect the pressure switch to a pressure source such as a hand pump connected to a gauge. Increase the source pressure to the setpoint of the switch until the switch changes state from open to close. Manually record the pressure value when the DMM indicates a “short circuit” or if using a calibrator it will record the value for you. Continue to increase the pressure until the maximum rated pressure. Slowly reduce the pressure until the switch changes state again, and resets from closed to open, then record the pressure. The setpoint pressure was recorded when the pressure was rising. The deadband value is the difference between the rising setpoint pressure and the falling pressure reset point.

- 10. 10 Suggested test tools Pressure switch testing–documented Classic methods for pressure switch testing have been superseded with the introduction of new pressure test tools. Today most pressure switches are tested with a pressure gauge mounted to a pump to supply and measure pressure, and a DMM set to continuity to verify the opening and closing of the switch. The technician or electrician making the test is required to interpret the pressure applied to the switch when the continuity beeper sounds indicating contact closure of the switch. A workable solution but new tools can make this task easier. Modern calibrators can automatically record the pressure applied when a pressure switch changes from open to closed and from closed to open. In doing so the switch set point and reset point and deadband are much easier to determine. Fluke 754 Documenting Process Calibrator-HART See pg 23 Fluke 750P Series Pressure Modules See pg 23 Fluke 700PTP-1 Pneumatic Test Pump See pg 31 Fluke 71X Hose Kit Accessory See pg 31
- 11. Hand Pump Pressure Module Pressure Input 11 • The key to a good switch test is repeatability. Repeatability is best achieved by applying a slow change in pressure to the switch as it approaches its set or reset pressure. • When performing the test find out where the switch sets and make sure the vernier/fine adjustment of your test pump has enough adjustment to vary the pressure up to the set point. In this way the pressure can be changed slowly capturing an accurate switch set point pressure. Repeat this procedure for the reset point. • With practice you can get the vernier of the pump within range of the set and reset point pressure and get excellent repeatability of your tests (within the limitations of the switch being tested). TECH TIPS To get started testing the switch, connect as shown above. In this example we will test dry contacts and continuity. To measure continuity for the test select resistance measurement. Then toggle to the source screen mode and select pressure to display the pressure generated by the hand pump and measured by the pressure module. Advance the calibrator mode to the split screen test mode. The next step is to describe the switch and whether it is normally open or closed at ambient pressure. The relaxed state of the switch is the reset state. The set state is the condition of the switch it changes to with ap- plied pressure or vacuum. In this example the switch is normally open and is expected to close when the pressure applied exceeds 10 psi. Next the allowable pressure variance of the switch set state and deadband size needs to be defined. In this example the ideal switch set value is 10 psi and is allowed +/- 1 psi of deviation. The allowable reset pressure is described in the deadband tolerance. In this instance the reset state must be more than 1 psi less than the found set pressure but not greater than 3 psi less than the found set pressure. Once the test tolerances are fully defined start the test. Increase the pressure until the calibrator captures the set state pressure value. Then decrease the pressure until the reset pressure is found. Repeat increasing and decreasing the pressure across the switch looking for repeatability in your set and reset pressure measurements. Once satisfied with the result press done to get the pass/fail evaluation of the switch. If the switch fails the test adjustment or replacement of the switch may be required. If the switch is adjusted repeat the test to document the As-Left condition of the switch before putting back into service. The test result is now documented and ready for upload to calibration management software. To perform the test: With a modern documenting calibrator you can test for dry contacts opening and closing on the switch or if you are using the Fluke 753 or 754 you can leave the switch connected to the live voltage and the calibrator will measure the changing AC voltage and interpret it as opening and closing of the switch. One cautionary note: it is always safer to test a de-energized circuit, but this is not always possible. Also, do not measure AC voltages above 300 V ac as that is the maximum rating of the 75X family. 480 V ac 3-phase voltages must be de-energized and disconnected from the switch if testing with the 75X family.

- 12. 12 Suggested test tools Gas custody transfer flow computer calibration Gas custody transfer flow computers that calculate flow in pipelines by measuring the differential pressure across a flow restriction, such as an orifice plate or other differential pressure flow device, require special calibration to perform at optimum accuracy. Gas flow computers make three primary measurements to calculate flow: volumetric flow (difference in pressure across the orifice plate), static pressure in a pipeline and gas temperature. A calculation is performed using this data to determine the actual mass and volume of the gas flowing through the pipeline. These calibrations can be made with three separate calibrators, a low pressure, high pressure and a temperature calibrator or use a multifunction calibration tool designed for this specific task. An example of a calibrator purposed for this task is the Fluke 721 or 721Ex. It has two built- in pressure ranges and the ability to measure temperature. The most popular configuration is 16 psi/1 bar on the low pressure (P1) sensor side and 1500/100 bar or 3000 psi/200 bar on the high pressure (P2) sensor side. It measures temperature using a precision RTD accessory and can display all three measurements at once if desired.

It is normally in- stalled with a 5 valve manifold. If so, closing the valves on the pipeline side of the manifold should isolate it. Be sure to follow local policy and safety procedures when performing this isolation step. Set the P1 sensor of the 721 to measure inH20 and the P2 sensor to measure PSI and the tempera- ture sensor to measure degrees Celsius or Fahrenheit as needed. Low pressure differential pressure calibration is performed using atmospheric pressure as a low side reference. Vent the low connection of the flow computer or pressure transmitter and connect the high pressure connection of the flow computer or transmitter to the low pressure port (P1) on the calibrator. Connect the computer (PC) to the flow computer serial or USB port. The PC will instruct the user to apply one or more test pressures to the flow computer or transmitter. For example, 0, 100 and 200 inH20. Squeeze the pump to get close to the test pressure and use the vernier or fine pressure adjust to dial in. Static pressure calibration will normally be applied to either the same high pressure port of the flow computer or both the high and low pressure ports. Refer to the manufacturer’s instructions for details. Connect the high pressure sensor input (P2) to the appropriate port on the flow computer or transmitter and to the high pressure test source. The PC will instruct the pressures for the user to apply from the pressure source. Temperature calibration of the temperature measurement on the flow computer is done with a single temperature point at the pipeline operating temperature. Insert the RTD probe into the test thermowell and allow time for the measurement to stabilize. The PC will prompt the user to enter the temperature measured by the calibrator. Remove the RTD from the test thermowell and the calibration is complete. Flow Computers with 4 to 20 mA inputs: Many flow computers utilize a low pressure, static and temperature transmitter to convert the measured parameters into 4 to 20 mA signals. In this instance these transmitters may need individual calibration if the test results are not satisfactory (see HART Transmitter Calibration application note or video for more details). Another source for errors in this configuration is the input A/D cards of the flow computer. These can be independently tested using a mA signal source from a loop calibrator. STEP 1 STEP 2 STEP 3 STEP 4 To perform the test: • Always center the vernier of your hand pump before starting any pressure calibration. This will allow you to increase or decrease the pressure when making fine adjustments. • Store the temperature probe in a protective case such as the built in slot of the 721 soft case. Exposing the RTD probe to mechanical stress can reduce the measurement accuracy of the probe. • Be careful to not connect the P1 low pressure side of the calibrator when doing high pressure calibrations or measurement or the sensor will be damaged and possibly rupture creating a dangerous condition. • Inserting the RTD probe prior to the pressure calibrations typically allows sufficient time to reach a stable temperature measurement.

Pressure gauges may be verified in the field or at the bench. Field calibration may save time, and allows for troubleshooting in the process environment. Multifunction calibrators make it easier to do this with one tool, and documenting calibrators make it easier to follow procedures, capture data and document results. Bench calibration provides an environment where the gauge can be cleaned, inspected, tested, and recertified under reference conditions for the best possible accuracy.

For hydraulic pressure gauges it’s important to remove any gas that might be trapped in the fluid in the gauge, calibrator, and connections by priming the system. When generating pressure allow a few moments for stability. Compare the reading of the gauge under test with the master gauge or calibrator. For hydraulic pressure gauges it’s important prime the system. This will remove any gas that might be trapped in the fluid in the gauge, calibrator or connections. When generating pressure allow a few moments for the measurement to stabilize. When using a hydraulic hand pump as a source it can take several minutes for the pressure to stabilize due to the thermodynamic effect of fluids.

TECH TIPS • Safety First! Check all fittings, adapters and connecting tubing ratings for pressures used. • Remember to tap analog gauges at each point due to friction in mechanical parts. • Gas is preferred for cleanliness requirements but use caution when generating pressures above 2,000 psi. • Industry standards usually desire calibration equipment to be 4-10 times more accurate than the device under test. • When in the field, connect pressure gauges through a manifold or “tee” connector. • Use adapter fittings when workloads require calibrating a wide variety of gauges. • Consider first, the in-use orientation of a device and use an angle adapter at the bench to achieve similar orientation. • Use a liquid-to-liquid separator to prevent contamination in hydraulic applications.

- 16. A deadweight tester is a proven method of pressure calibration that is usually chosen for bench applications when accuracy and reliability are the top requirements. Calibrations are performed at the bench for convenience and to maintain reference conditions. The bench is a convenient location to clean, inspect, calibrate and repair with all the necessary equipment available. Reference conditions are necessary to achieve the reference accuracy of the device under test and the calibration standards. Reference accuracy may be required to maintain the necessary test uncertainty ratios (TUR). 16 Suggested test tools Calibrating at the bench with a deadweight tester P3100, P3200, or P3800 Series Hydraulic Dead- weight Tester See pg 29-30 6531, 6532 Electronic Deadweight Tester See pg 30 P3000 Series Pneumatic Deadweight Tester See pg 29 Using liquid: Using gas:

Measurement points should be distributed uniformly over the calibration range. Calibrated weights are placed on the instrument corresponding to the measurement points. Pressure is added with an internal pump or screw press until the piston holding the weights begins to float. The piston and weight are spun by hand to minimize friction. While the piston is floating the reading on the device under test is com- pared to the pressure corresponding to the sum of the selected weights. • Deadweight tester weights are calibrated to match a wide range of pressure units. • Local gravity often is the largest factor affecting accuracy. Use Fluke PRESSCAL software to achieve accuracy of +/- 0.008%. • To increase the number of available set points, use incremental weight sets. • Forgo wrenches or PTFE tape by using adapters to fit multiple sizes and types of devices with leak tight seals to 20,000 psi. • Safety First! Choose fittings, tubing and seals with pressure ratings above the full scale of the instrument. • Hydraulic systems are preferable to gas systems for pressures above 2000 psi due to safety and ease of use. • Consider achieving cleanliness using distilled water as a media or use a liquid separator from Fluke instead of gas. • Lubrication can improve performance by using oil when it is allowed.

- 20. 20 Suggested test tools Use and selection of hand pumps and pressure test gauges for field pressure testing It’s important to select the proper pump and gauge to match the testing application at hand—a good guideline is the testing device should be 4-10 times more accurate than the device being tested. To achieve this, match the measurement to be made as closely to the full scale value of the test gauge. This delivers the best accuracy from the gauge.

The source pressure can be adjusted until the device under test is reading a nominal pressure or until the reference gauge reads the nominal pressure. • The key to a good experience in using a hand pump, either pneumatic or hydraulic, is to test and debug your test setup in the shop before going to the field. Minimizing the number of pressure connections minimizes the probability for leaks. Mount the test gauge carefully to the test pump in the shop. • Be sure to consider the hoses that connect from the hand pump to the device to be tested. There are a variety of specialty “no tools required” connectors to connect to the test hose to make this easy. If these connectors are not available be sure to have a variety of adapters, wrenches and PFTE sealing tape to be able to connect from the test hose to the input port of the device for testing. If using “push fit” hoses it is likely they will eventually leak. Each time - a push fit hose is connected, it leaves a mark on the test hose and eventually does not seal well. To eliminate the leak cut off the affected portion of the test hose so there is a clean surface to connect to. This process will need to be repeated with use. • When attempting to get maximum pressure out of a pneumatic pump, adjust the fine adjust vernier all the way to down to the stop so turning the vernier increases the pressure. When approaching the target pressure use the vernier to increase to your target pressure. • When using hydraulic hand pumps remember the thermodynamic effect. Once any fluid is compressed, the temperature increases and the fluid expands. This becomes obvious when pumping to a target pressure with a hydraulic pump. Once the target pressure is met the fluid has expanded. As the fluid cools and contracts the pressure quickly bleeds down until it reaches temperature equilibrium, this can take 5 minutes or more. Once the temperature stops changing, dial the desired pressure back in with the vernier adjuster.
