Five steps in choosing a thermometer readoutand reference probe:12345stepstepstepstepstepChoose the best thermometer readoutfor the industrial sensor application.Evaluate if additional calibration is required.Select the reference probe consideringthe temperature range of the sensorapplication and immersion depth required.Determine the combined systemaccuracy of the readout and referenceprobe selected.Verify that the readout and probe systemselected will provide the accuracy neededto calibrate the sensor under test.1502A1504152315291524Several questions should be considered in selecting the right thermometer readout:•Which temperature sensors need to be calibrated—PRTs/RTDs, thermistors, thermocouples?•Will the readout be used in the field or in a calibration lab?•How many channels are needed on the readout?•What level of data logging, graphing and recording features are required?•Is temperature source control of dry-wells, baths, or furnaces desired to help automate sensor calibration? The following table provides a guide for selecting a readout with these technical needs in mind.2No calibration included. Check with your distributor for calibration options.3NIST traceable calibration included. NVLAP accredited calibration optional.4“Basic Accuracy” includes calibration uncertainty and short-term repeatability. It does not include long-term drift.It is important to select a reference probe that covers the full temperature range of the sensor application. Table 2 summarizes temperature ranges for selected reference probes.Table 2: Temperature ranges for select Fluke Calibration probes.Consider the lengthMake sure the reference probe is long enough to reach the bottom of the dry-well or the sensing element of the unit under test in a bath. The sensing element of a PRT is usually in the bottom one inch of the probe. A thermistor sensing element is only a few millimeters at the bottom of the probe. The measurement junction of a thermocouple is where the two dissimilar wires connect.To ensure the reference and the unit under test are at the same temperature during comparison calibration, the sensing element of the unit under test needs to be vertically aligned with the center of the sensing element of the reference probe. Also, inaccurate measurements can occur if either the reference probe or the unit under test is not sufficiently immersed in the dry-well or bath.Consider the diameterMinimum immersion is the minimum depth the probe needs to be inserted into the bath or dry-well for accurate measurement. It is determined by the diameter of the selected probe and the length of its internal sensing element.A general rule is the minimum probe immersion needs to be 15 times the probe diameter plus the sensor length. Fluke Calibration 6-inch and 9-inch PRTs have a 3/16 inch diameter rather than a 1/4 inch diameter and can be a better choice for calibrating shorter probes. See Table 2 for minimum immersion depths for select probes.Safety and other considerationsSome applications may require exposing more of the probe to extreme temperatures than is desirable. Exposing the probe handle to extreme temperatures poses safety concerns for the user, since it may be too hot or cold to touch without safety gear. Also, the transition junction is located inside the probe handle base where the probe connects to the cable and can be damaged by extreme temperatures. Finally, if high temperatures in the transition junction cause the insulation resistance to decrease below 100 MΩ, the performance of the probe might also decrease.For example, a 5615-12 Secondary Reference PRT can operate over a range from –200 °C to 420 °C. However, the 5615-12 transition junction range is –50 °C to 200 °C. This means the probe is designed to measure tempera-tures from –200 °C to 420 °C, but the probe will be damaged if the handle is exposed to temperatures outside the range of –50 °C to 200 °C. Even if the probe is not damaged, touching a probe handle that is extremely hot or cold with bare hands could result in burns.In this example, the 5615-12 can be used to calibrate sensors as low as -200 °C, but would be damaged if placed in a freezer at -80 °C since the transition junction lower limit is -50 °C. For a freezer application, the 5606 Full Immersion PRT would be the right choice since the probe and transition junction can operate at a lower limit of -200 °C.Table 3 shows the system accuracy for Fluke Calibration 1523/1524, 1502A/1504, 1529, and 1586A Super-DAQ thermometer readouts and selected reference probes (5615, 5627A, 5628, 5605, 5610) or Type T and K thermo-couples. For example, the 1586A Super-DAQ with DAQ-STAQ Multiplexer and a 5628 Secondary Standard PRT has a system accuracy of ± 0.011 °C at 0 °C.Reference probes are connected to the thermometer readout, but readouts don’t all share the same connection scheme. When a readout and probe are paired, be sure to choose a model terminated with the right connector. For your convenience, probe models with the correct termination for the readout are shown in Table 3. Note that the readout accuracy with a 5606 probe assumes that the probe has received an optional calibration.A Lemo-to-Unversal Thermocouple adapter 2373-LTC is available for connection to thermocouples.The 1524 can measure two channels at a time, but only one channel can be a thermocouple.5615-6 range is -200 °C to 300 °C. 5615-9, -12 range is -200 °C to 420 °C. 5627A-6, -9 range is -200 °C to 300 °. 5627A-12 range is -200 °C to 420 °. Connector type: DThis is a standard DIN connector and does not contain a microchip with the probe coefficients.5615-6 range is -200 °C to 300 °C. 5615-9, -12 range is -200 °C to 420 °C. 5627A-6, -9 range is -200 °C to 300 °C. 5627A-12 range is -200 °C to 420 °C.The 1529 works with probes that are terminated with the type L connector. These are gold plated mini spade lugs. The 1529 is also compatible with gold pins, mini banana plugs, and bare wire probe terminations. This version of the 1529 is also compatible with mini thermocouple connectors.5616-6 range is -200 °C to 300 °C. 5615-9, -12 range is -200 °C to 420 °C. 5627A-6, -9 range is -200 °C to 300 °C. 5627A-12 range is -200 °C to 420 °C. Connector type: LThe 1529 works with probes that are terminated with the type L connector. These are gold plated mini spade lugs.The 1529 is also compatible with gold pins, mini banana plugs, and bare wire probe terminations.5615-6 range is -200 °C to 300 °C. 5615-9, -12 range is -200 °C to 420 °C. 5627A-6, -9 range is -200 °C to 300 °C.5627A-12 range is -200 °C to 420 °C.Connector type: LThe 1586A works with probes that are terminated with the type L connector. These are gold plated mini spade lugs.The 1586A is also compatible with gold pins, mini banana plugs, bare wire, and mini thermocouple probe terminations.5615-6 range is -200 °C to 300 °C. 5615-9, -12 range is -200 °C to 420 °C. 5627A-6, -9 range is -200 °C to 300 °C. 5627A-12 range is -200 °C to 420 °C. Table 3: Readout accuracy with selected probes.The calibration system comprised of a readout and reference probe needs to have a higher level of accuracy than the temperature sensor being calibrated. A “test accuracy ratio” (TAR) of 4:1 or 3:1 is commonly used as a guide-line. A 4:1 TAR means the calibration system is four times more accurate than the sensor being calibrated. In this example, the system with a 4:1 TAR would be more accurate than a system with 3:1 TAR.Table 4 shows the minimum system accuracy required to calibrate common temperature sensors (Grade A and B PRTs, Type T and K thermocouples). For example, a readout and reference probe system with a combined accuracy of ± 0.06 °C would be needed to calibrate a Grade B PRT at 0 °C with a 4:1 TAR.Assume the 1586A Super-DAQ with DAQ-STAQ Multiplexer and a 5628 Secondary Standard PRT were selected as the readout-and-probe system. The 1586A/5626 system would be a good choice to calibrate a Grade B PRT. The 1586A/5626 system accuracy of ± 0.011 °C at 0 °C is much better than the ± 0.06 °C system accuracy at 0 °C required to calibrate a Grade B PRT with a 4:1 TAR.*ASTM Specification E1137 “Standards Specification for Industrial Platinum Resistance Thermometers”Table 4: Minimum system accuracy required for PRT and thermocouple calibration (± °C).Factory calibrationIt is standard practice for all Fluke instruments to include a factory calibration that is traceable to national stan-dards. Traceability means that there is an unbroken chain of comparisons between the instrument and a national standard providing assurance that measurements obtained with the instrument correlate to a national standard at a particular level of uncertainty.In a few cases, probes such as the 5606 do not include a factory calibration, but a calibration is an avail-able option. If you purchase an uncalibrated probe, then the chain of traceability is broken until a calibration is performed.With many Fluke instruments, the factory calibration is also accredited to ISO 17025. Table 5 summarizes the factory calibrations for the instruments discussed in this guide. Typically, type T and type K thermocouples are provided uncalibrated by the manufacturer. Check with your distributor about temperature instrument calibrationoptions available.Table 5: Factory calibration included with selected Fluke readouts and probes.System calibrationIn addition to a factory calibration for both the probe and read-out, you may desire to verify the performance of the probe andreadout together with a “system calibration.” This system cali-bration provides a higher level of assurance that the instruments are performing as expected when combined together and all probe coefficients are entered correctly into the readout. Check with your distributor about system calibration options available. SummaryThis guide has covered the steps to follow when choosing a readout and probe appropriate for your application. Tempera-ture range of the application and accuracy required are key considerations, but other factors discussed in this guide should be evaluated. If you have a special application such as measur-ing surface temperatures, liquids with high pH, air temperature, or temperature inside an enclosure such as a freezer or oven, please consult a Fluke Calibration temperature specialist to assist with your equipment selection.Fluke CalibrationPO Box 9090, Everett, WA 98206 U.S.A.Fluke Europe B.V.PO Box 1186, 5602 BDEindhoven, The NetherlandsWeb access: http://www.flukecal.euFor more information call:In the U.S.A.

Application NoteBecause pressure is one of the more widely measured param-eters in process industries, it is a critical function of a document-ing process calibrator. Fluke’s pressure modules cover a wide range of pressures and maintain accuracy over a wide tempera-ture range, from 0°C to 50°C (32° F to 122°F). The pressure measurement portion of the Fluke 700 Series Documenting Process Calibrators is separate from the main unit to facilitate connection to fixed or bulky equipment and to provide mul-tiple pressure ranges for a single calibrator.A large selection of gage and differential modulesA family of 27 pressure modules covers the most common pres-sure calibrations from 0-10" H2O (0-2.5 kPa) to 0-10,000 psi(0-70,000 kPa).Gage pressure modules have one pressure fitting and measure the process pressure with re-spect to atmospheric pressure. Differential pressure modules have two pressure fittings and measure the difference between the applied pressure on the high fitting versus the low fitting. Each module is clearly labeled for range, overpressure specifi-cation, and materials compatibil-ity. A metric adapter is included with all but the P29 through P31 high pressure modules. Figure 1 shows the two types.Quick and easy measurements Fluke 700 Series pressure mod-ules are easy to operate. To measure pressure, the technician disconnects the pressure mea-suring transmitter from the process, plumbs the pressure module to a pressure source, and connects the pressure module cable to the calibrator. Pressure is applied, measured by the pres-sure module, and displayed digi-tally on the calibrator. At thetouch of a button, the pressuremay be displayed in any of 10different pressure units. Becausethe 700 Series calibrators cancapture readings electronically,there’s no need to write downresults. The calibrators automati-cally time-stamp and store allsaved measurements, savingtime, and eliminating errors asso-ciated with making manual nota-tions in the field. These self-documenting capabilities areimportant in ensuring accuratemaintenance. They are also veryhelpful in collecting calibrationdata to support compliance withdocumentation standards, includ-ing those established by OSHA,the FDA, the EPA, and ISO 9000.Pressure module performanceFluke 700 Series pressure mod-ules are highly accurate, withsimply stated specifications thatapply from 0% to 100% of fullspan and from 0°C to 50°C (32°Fto 122°F)—a factor that sets themapart from other pressure calibra-tors. Most ranges have total un-certainties of 0.05% of full scale(see Table 1, page 2).This performance is possiblethrough the innovative applica-tion of mathematics and micro-processor power. Fluke pressuremodules have silicon piezo-resistor sensors which consist ofa resistive bridge fabricated in asilicon diaphragm. Pressure ap-plied to the diaphragm causes achange in the balance of thebridge which is proportional tothe applied pressure. The bridgebalance change is not linear andis very sensitive to temperature.However, since these effects arequite stable with time andthrough repetitive changes ofcondition, the sensors can bevery accurate in measuring pres-sure over a wide temperaturerange, provided they are care-fully characterized.During manufacture, Flukepressure modules are character-ized by reading temperature andpressure at more than 100points. A least-squares regres-sion is used to calculate the coef-ficients of polynomial expressionfor pressure. The coefficients,unique to that pressure module,are stored in the module’smemory.Fluke 700 Series Pressure ModulesFigure 1. Gage and Differential pressure modulesEach module has its own microprocessor, allowing it to run the measurement circuitry and to communicate digitally with the calibrator. When con-nected to the calibrator, the coef-ficients are uploaded from the pressure module to the calibrator.Then, when pressure measure-ments are made, raw sensor values for pressure and tempera-ture are digitally loaded to the calibrator, where the raw sensor values and coefficients are manipulated to derive and dis-play the pressure reading. This innovative technique provides several benefits:1.Digital communication elimi-nates errors due to poor connections and electrical interference.2.The modules are inherently temperature-compensated from 0°C to 50°C (32°F to 122°F), with no derating for temperature effects.Figure 2. 700 Series Pressure Modules are overmolded with protective urethane and sealedagainst dirt, dust and moisture. All fittings are made of 316 stainless steel or Hastelloy C276and have internal mechanical supports3.The modules are fully inter-changeable because all signal processing is handled in the pressure module itself and then communicated to the calibrator in digitized form.Modules are calibrated inde-pendently of the calibrator,and can be used with any 700Series calibrator. Each module has its own serial number to facilitate traceability.Sensor protection in isolated modules Many of these modules (see Table 1) incorporate a stainless steel diaphragm to isolate the sensor.With these modules, any medium that is compatible with stainless steel can be used on the high side of the module.Rugged construction The pressure modules are de-signed to operate accurately and reliably despite the rough han-dling and harsh environmental conditions often found in process plants. A urethane overmolding protects against shock if a mod-ule is accidentally dropped and also seals against dirt, dust, and moisture. The module case is held together with screws con-nected to brass-reinforced seats,and all the pressure fittings,which are constructed of 316stainless steel, have internal mechanical supports. Pressure connections are 1/4" NPT. A BSP/ISO adapter is also provided on all but the P29, P30 and P31.Small and lightweight Since process technicians might need to carry two or more pres-sure modules along with the calibrator, the modules are small and lightweight.Remote sensor A one-meter cable between the pressure module and calibrator reduces the length of connecting tubing to the pressure source.The remote pressure head also provides an extra margin of safety and convenience by re-moving the calibrator and opera-tor from the pressure source.Table 1.

Common mode pressure—the underlying common pressure (or static pressure) within a sys-tem from which a differential measurement is being made.D/P: Differential pressure, (pronounced DP)—other names used to mean the same thing are d/p cell, d/p transmitter and ∆P transmitter (where ∆ is delta or differential). This is the most common type of transmitter used in most process industries. It can be used to measure level, flow, pressure, differential pressure, and density or specific gravity. With some modifications, it can measure such things as tem-perature and oxygen purity. The d/p transmitter can be pneu-matic, electromechanical, or solid state. It can also be a smart transmitter. A typical large pro-cess plant can have hundreds or thousands of d/p transmitters in service.PSI—pounds per square inch(same as psig).PSIA—pounds per square inchabsolute.PSID—pounds per square inchdifferential.PSIG—pounds per square inchgage (same as psi).Square root extractor—aninstrument or software programthat takes the square root ofinput and puts the result on itsoutput. Square root extraction isneeded to linearize many flowsignals. Example: orifice plates,venturis, target flow meters, andpitot tubes all require thetransmitter’s output signal to belinearized. Mag flow meters,turbine flow meters, Dopplerflow meters, and vortex shed-ding flow meters don’t requiresquare root extraction.Static pressure—the zero-veloc-ity pressure at any arbitrarypoint within a system.Wet/dry differential—a differ-ential pressure transducer ortransmitter that uses a metaldiaphragm at the wet portwhere fluids can be applied, andno diaphragm at the dry port.The dry port exposes the sensormaterial to the medium, so onlyclean dry gas can be applied tothis port.Wetted parts—the diaphragmand pressure port material thatcomes in direct contact with themedium (gas, liquid).Gage pressure—the pressurerelative to atmospheric pressure.Gage pressure = absolute pres-sure minus one atmosphere.Gage pressure transducer—a transducer that measures pres-sure relative to atmosphericpressure.Ideal Gas Law—combiningBoyle’s Law and Charles’ Law,results in the Ideal Gas Law:PV=nrT, where nr is constant fora particular gas analogous to thenumber of molecules and therelative size of the molecule.I/P (I to P)—a current to pres-sure transmitter. A common in-strument in modern industrialplants. A typical large paper millor refinery could have 5,000 I/Psin use.Line pressure—the maximumpressure in the pressure vesselor pipe for differential pressuremeasurement.Orifice plate—a very low costand common primary sensingelement (PSE) for measuringflow. It must be used in conjunc-tion with a d/p cell. It creates aventuri and a resulting P isdeveloped across the platewhose square root is propor-tional to flow.P/I (P to I)—a pressure to cur-rent transducer.Pneumatic relay—refers to apneumatic instrument that per-forms a function to its input andprovides the result on its output(Example: square root extractor,adder, etc.).Fluke-700 PCK Calibration KitThe Fluke 700PCK Pressure Cali-bration Kit makes it possible to calibrate your pressure modules at your facility using your own precision pressure standards.The kit consists of a power sup-ply, an interface adapter, appro-priate cables, and Fluke 700PC Pressure Module Calibration soft-ware.
