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 Pressure Applications 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.

Model 754 requires the correct range 750P pressure module for pressure testing. Model 753 can be used for the same applications as model 754 except for HART device calibration. Model 725 and 726 can be used for the same applications as model 753 except for documenting and live contact testing of switches. 24 Pressure Applications Pressure Applications 25 Calibrating a HART smart pressure transmitter Pressure Module 754 DOCUMENTING PROCESS CALIBRATOR Hand Pump Pressure transmitter manufacturers have improved the accuracy and technology designed into these smart pressure measurement devices. Many conventional calibration tools have become inadequate 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 transmitters. It can also document transmitter performance before and after adjustment and calculate pass/fail errors. + – – PWR/ COMM TEST Pressure Input mA Measure, 24V Loop To perform the test: STEP Isolate the transmitter from the process being measured and its loop 1 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. STEP Connect the mA measurement jacks of the 754 to the transmitter. 2 STEP Connect the pressure module cable to the 754 and connect the 3 transmitter test hose from the hand pump to the transmitter. STEP Press the HART button on the calibrator to see the configuration of 4 the transmitter. STEP Press HART again and the calibrator will offer the correct measure/source 5 Suggested test tools 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. STEP Select adjust and trim the transmitter’s pressure zero, mA output signal 6 and input sensor. STEP After adjustment select As-Left, document the condition of the transmitter 7 26 Fluke 754 Documenting Process Calibrator-HART Fluke 700G Precision Pressure Gauge Calibrator See pg 5 See pg 13 Pressure Applications Fluke 750P Series Pressure Modules Fluke 700PTP-1 Pneumatic Test Pump See pg 12 See pg 23 after adjustment and if the test passes, it is complete.

TECH TIPS Sometimes it is necessary to trim the input sensor of the transmitter more than once. It is critical that the pressure module be zeroed before test and adjustment. For best ßadjustment success: • After pressing Fetch for the pressure measurement, select the trim button quickly before the pressure measurement 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 pressure module, select a lower range pressure module for best results. • If performing higher pressure calibrations with a hydraulic pump, use the correct 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 transmitter, 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.

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. mV TECH TIPS Hz REL mA A V V mA OFF mA OUTPUT Hand Pump 250 HART LOOP POWER mA OUTPUT 0-24mA SOURCE A SIMULATE mA COM V Pressure Input To perform the test: When you use a Fluke 754 or 3130 to automate the pressure switch calibration, vary the applied pressure slowly, back and forth across the setpoint and reset points. The display will make it apparent that the set/reset has changed and the actuals will be logged. Setup STEP Safely disconnect the device from the process it controls. 1 STEP Connect the calibrator or DMM to the common and NO (normally open) 2 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. STEP Connect the pressure switch to a pressure source such as a hand pump 3 connected to a gauge. Rising pressure STEP Increase the source pressure to the setpoint of the switch until the switch 4 Suggested test tools 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. Falling pressure STEP Continue to increase the pressure until the maximum rated pressure. 5 Slowly reduce the pressure until the switch changes state again, and resets from closed to open, then record the pressure. Calculation STEP The setpoint pressure was recorded when the pressure was rising. 6 Fluke 754 Documenting Process Calibrator-HART See pg 5 30 Pressure Applications Fluke 719Pro Electric Pressure Calibrator Fluke 3130-G2M Portable Pressure Calibrator See pg 11 See pg 14 Fluke 750P Series Pressure Modules See pg 12 Fluke 700PTP-1 Pneumatic Test Pump The deadband value is the difference between the rising setpoint pressure and the falling pressure reset point.

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. 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. STEP To get started testing the switch, connect as shown above. In this example 1 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. STEP The next step is to describe the switch and whether it is normally open 2 Suggested test tools 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 applied 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. STEP Once the test tolerances are fully defined start the test. Increase the 3 Fluke 754 Documenting Process Calibrator-HART See pg 5 32 Pressure Applications Fluke 750P Series Pressure Modules See pg 12 Fluke 700PTP-1 Pneumatic Test Pump See pg 23 Fluke 71X Hose Kit Accessory See pg 23 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. • 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).

Pressure switch video Pressure switch application note Pressure calibration application note Pressure Applications 33 721 PRESSURE CALIBRATOR Gas custody transfer flow computer calibration F1 F2 F3 ZERO V mA 7.21psi 30V 24mA MAX COM 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 builtin 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. Pump Close valves 720TRD RTD Probe Close valves Fluid stream Fluid stream To perform the test: To get started, isolate the flow computer from the pipeline. It is normally installed 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 temperature sensor to measure degrees Celsius or Fahrenheit as needed. STEP Low pressure differential pressure calibration is performed using 1 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. STEP Static pressure calibration will normally be applied to either the same 2 Suggested test tools 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. TECH TIPS • 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. STEP Temperature calibration of the temperature measurement on the flow 3 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. STEP Flow Computers with 4 to 20 mA inputs: Many flow computers utilize a Fluke 721 Precision Dual Range Pressure Calibrator See pg 12 34 Pressure Applications Fluke 700G Precision Pressure Gauge Calibrator See pg 13 Fluke 754 Documenting Process Calibrator-HART See pg 5 Fluke 750P Series Pressure Modules See pg 12 4 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.

HART pressure and HART smart RTD transmitter 754 videos Custody Transfer calibration application note HART transmitter calibration Pressure Applications 35 Verifying process gauges, analog and digital Both analog and digital process gauges need to be verified to detect errors related to drift, environment, electrical supply, addition of components to the output loop, and other process changes. 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. TECH TIPS Pressure Module • Safety First! Check all fittings, adapters and connecting tubing ratings for pressures used. Hand Pump Pressure Input • Gas is preferred for cleanliness requirements but use caution when generating pressures above 2,000 psi.

Mount the test gauge carefully to the test pump in the shop. 1 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.

Fluke 700G Precision Pressure Gauge Calibrator See pg 13 42 Pressure Applications Fluke 700PTPK2 Pneumatic Test Pressure Kit • 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.

Interpreting Specifications for Process Calibrators, Application Note • 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. Pressure Applications 43 INTRODUCTION Temperature devices in process manufacturing environments provide measurements to the process plants’ control systems. The performance of these temperature instruments is often critical to optimized operation of the process manufacturing plant or proper functioning of the plant’s safety systems. Temperature Applications Process temperature instruments are often installed in harsh operating environments, causing their performance and the performance of their sensors to shift or change over time. Keeping these devices measuring temperature within expected limits requires periodic verification, maintenance and adjustments.

However, if a problem is suspected with a temperature sensor, sensor calibrations can be performed separately from the calibration of process electronics. ENTER 100.00°C F1 F2 F3 Field checks of temperature sensors can be easily performed with a dry-block or Micro-Bath. For best results, a full calibration of a temperature sensor is performed at the bench. F4 100.00°C F1 F2 F3 F4 To perform the test: STEP Isolate the sensor from the process. 1 STEP Fully immerse the sensor into a precision temperature source, such as a 2 dry-well or bath capable of covering the required temperature range. TECH TIPS • Dry-wells have inserts that are interchangeable and have a variety of hole patterns to accommodate various probe sizes. • To achieve published performance levels, the insert’s hole size should be no more than a few hundredths of an inch larger than the probe being calibrated. • Avoid placing fluids in a dry-well. If fluids are required, use a Micro-Bath instead. • If climbing a ladder is required, dry-wells are safer than baths, and handheld dry-wells may be the most convenient.

F1 F2 F3 F4 F1 F2 F3 F4 They should be tested during commissioning and again when removed from a process to verify that tolerances were met. Additionally, thermocouples may be tested at regular calibration intervals and when suspected of failing to meet their performance specifications. Often thermocouples need to be calibrated prior to use for mapping a temperature controlled enclosure, or they have to be calibrated for use as a temperature standard. Due to the unique characteristics of thermocouples, they are best calibrated in situ (in place) by comparison to a temperature standard. However, in situations where that is not practical, it is necessary to remove the thermocouple and place it in a precision temperature source such as a dry-well. To perform the test: STEP Isolate the sensor from the process. 1 STEP Fully immerse the sensor into a precision temperature source such as a 2 dry-well or bath capable of covering the required temperature range. STEP To check the calibration of the thermocouple separately from control 3 TECH TIPS system temperature indicator, disconnect the thermocouple from the electronics. • Depending on the thermocouple, incorrectly setting reference junction compensation may result in a temperature error of around 23 °C. Also, the reference junction compensation accuracy of the meter may be the largest contributor to the error. • Thermocouple wire generates a voltage whenever two adjacent points along the wire are at different temperatures. • The whole length of the wire (not just the probe tip) generates the voltage. This means the whole wire needs to be treated carefully and considered during the calibration.

Changes in ambient temperature should be compensated for automatically. • When testing 3-wire RTD circuits make sure to connect all three wires from the sourcing RTD simulator to the device being tested. Shorting out the compensation wire at the transmitter defeats the lead compensation circuit and introduces measurement errors. for thermocouple testing, starting at step 3.

In situ verification at a single point may be the only way to know whether an instrument is performing as expected. A single point verification is most effective over a narrow temperature range and when combined with other trends and information related to the process and equipment. It also requires the process not to be in a dynamic state of change.

Usually this is accomplished with a test well that is installed in a location adjacent to the sensor to be tested. 12 V DC T2 To perform the test: STEP The test well (thermowell) should be within a few inches of the 1 temperature transmitter and sensor assembly to be tested. STEP Make sure that the probe of the temperature standard is long 2 enough to reach the bottom of the test well and that air gaps between the probe and well are minimized. STEP Wait for the temperature standard to reach the temperature of 3 the test well. This will take a few minutes. STEP Check for temperature stability. A graphing digital thermometer 4 NEXT TECH TIPS • For this type of application a battery powered digital thermometer is usually preferred. • A graphing display helps the technician visualize trends such as stability quickly and easily. • Ensure that both the probe and the readout of your temperature standard have traceable calibration certificates from a competent laboratory. • If the probe and readout separate from each other, smart connectors, which include probe calibration constants, provide a best practice method of ensuring that the readout is using the correct probe calibration in its temperature readings. such as the 1524 makes stability easier to recognize.

Temperature measurement and calibration: What every instrument technician should know Industrial temperature readout and probe selection guide Process Calibration Tools: Temperature Applications Temperature Applications 53 NTING PRO CESS CAL Temperature switch and controller testing in the field Temperature switches and controllers are commonly used in small processes and in control loops where a programmable logic controller (PLC) or larger distributed control system (DCS) are not warranted. Temperature controllers provide both switching capability based on rising and dropping temperatures, as well as a local indication of the measured temperature. Most temperature controllers have some form of tuning, using damping and PID (Proportional, Integral and Derivative values) for smoothing out the measured process temperature, reducing variability. IBRATOR TECH TIPS 200.0° C MENU ENTER To perform the test: To use a thermocouple simulator to test a switch with a thermocouple input: STEP Disconnect the process measurement sensor. 1 Closed 50 C Deadband Open Setpoint Reset High Limit Process Variable Open Reset Deadband 20 C Closed Setpoint The terminology around switches can be confusing. The set state of the switch is the action the switch takes when an input stimulus above or below a specified value is applied. This stimulus can prompt an action such as closing a switch, which in turn starts or stops a motor, or opens and closes a valve. The reset point is considered the relaxed state of the switch, which is typically referred to as “Normally Open” or “Normally Closed.” This describes the default condition of the switch. Lastly, deadband is the band of temperature equal to the difference between the temperatures where a switch sets, and resets. See illustration at left. STEP Connect the mini-connector from the test wires to the TC source 2 connection of the calibrator (figure above). STEP Connect the calibrator resistance measurement terminals to the 3 switch contacts to measure continuity. STEP Set the calibrator to source/simulate the correct thermocouple type 4 and to measure resistance. STEP Configure the calibrator for the switch test describing the expected 5 setpoint temperature, allowable deviation and expected deadband values. STEP Run the test and evaluate the test results.

If it does not agree, the device’s input A/D may need adjustment per manufacturer’s procedure. • When testing a switch with damping (delay of output change for a change on the input) set, it might be necessary to test the switch manually by slowly changing the temperature in small tests. • When testing a mechanical temperature switch (no external sensor), use a field temperature bath calibrator for best results. • To test live switch contacts switching 24 V dc or 120240 V ac, select a calibrator that can measure these live voltages, such as the Fluke 75X family of Documenting Process Calibrators. Most other temperature calibrators can only measure continuity changes when testing switches.

Temperature Switch sets - closed Temperature switches are often calibrated or tested for safety reasons to determine how accurate and repeatable the device is. The temperature at which a switch activates is called the set point and is an important value that needs to be verified during testing. Another critical safety related value is called the deadband. Below the low end of the deadband, the heating system turns on. Above the high end of the deadband, the heating system turns off. Switch tests may be operated manually or automatically. If the electronics are not built into the dry-well for a switch test, then a DMM will be needed to determine the open/ close condition. Metrology Wells and most Field Metrology Wells have built-in routines to automate switch testing. Deadband Set-point Reset Switch resets - open • Set the scan rate to a low value, i.e. 1.0 °C per minute, for better accuracy. • If the scan rate is too low, the duration of the test may be longer than necessary. Time To perform the test: STEP Isolate the switch from the process. 1 STEP Fully immerse the switch into a precision temperature source such as a 2 dry-well or bath capable of covering the required temperature range.

Industrial Temperature Calibrators Workload Matrix Process Calibration Tools: Temperature Applications Temperature Applications 59 Measuring (d) distance Infrared thermometer test and calibration d Manufacturer recommended large target 561 HVACPro IR THERMOMETER • Emissivity makes a big difference in infrared temperature measurement. 199.3 Smaller target Common errors include pressing the infrared calibrator too close to the hot surface of the calibrator or simply moving the infrared thermometer back and forth until the desired reading is achieved. The manufacturer will have calibrated the infrared thermometer at a specific distance with a source that meets certain size requirements and has a specific emissivity (often but not always 0.95). To have a meaningful calibration that determines whether the instrument continues to operate within its design specifications, those conditions need to be reproduced as closely as possible. TECH TIPS IR thermometer spot size Infrared thermometer calibrations can be accurate with the proper setup and planning. It’s important to choose a calibrator with a radiometrically calibrated target that is large enough to accommodate the recommended calibration distance of common infrared thermometers, along with their various fields of view. = IR thermometer field of view To perform the test: STEP Allow at least 15 minutes for the IR thermometer to reach the 1 temperature of the shop or laboratory. STEP Set the radiation source to the desired calibration temperature. 2 Depending on the temperature range a low, high, and midpoint temperature may be chosen. STEP If the infrared thermometer has an emissivity setting, it should be set to 3 match the calibrated emissivity of the source. STEP Position the infrared thermometer at the manufacturer’s recommended 4 calibration distance. STEP Center the infrared thermometer on the calibrator surface. Do this by 5 Suggested test tools adjusting the aim slightly side to side and up and down to maximize the signal.

Emissivity makes a difference How to Calibrate an IR Thermometer webinar Infrared Temperature Calibration 101 application note Infrared Thermometer Calibration – A Complete Guide Temperature Applications 61 Loop calibration with a temperature transmitter at the bench TEST DC PWR – ++ – TECH TIPS In industrial process industries, temperature measurement equipment usually has two components: a sensing device such as an RTD or thermocouple and a transmitter to read and relay the signal to the control system. All sensors, including RTDs, drift with time. Thus, testing the transmitter and not the sensor could result in misjudgment regarding a system’s performance. To avoid this potential problem, process instrument manufacturers recommend including the temperature sensor in loop calibration to prove the effectiveness of the entire system. 100.00°C F1 F2 F3 F4 • Streamline the process with automation and provide documentation using a Fluke 754. • Seventy-five percent of the errors in a temperature measurement system comes from the sensor. • At minimum, you need a calibrator, and a device to measure 4-20 mA and power the loop. To perform the test: • Choose a temperature standard with a 90 degree angle bend to ensure both the temperature standard and the transmitter fit in the dry-well at the same time. STEP Isolate the sensor from the process. 1 STEP Fully immerse the sensor into a precision temperature source such as a 2 Suggested test tools dry-well or bath capable of covering the required temperature range. STEP Connect the temperature standard and 4-20 mA output of the 3 transmitter to a suitable meter or calibrator (for example, the process electronics on a Fluke Field Metrology Well or the inputs of a Fluke 754). STEP Power the loop. (The Fluke 754 and the process electronics in a 4 Field Metrology Well have this capability.) STEP Adjust the temperature of the bath or dry-well to each of the test points. 5 (With Field Metrology Wells, these test points can be preprogrammed and automated.)
