## **Overview** 

NI offers thermocouples and RTDs for your measurement and automation systems. These sensors are available in versatile configurations – field-cuttable probes and ready-made sensors. NI also offers spools of thermocouple wire and extension wire. 

## **Thermocouples** 

Thermocouples are the most popular temperature measurement transducers available. Because of their low cost and wide temperature acceptance range, you can use thermocouples for a wide variety of applications in all industries. All NI thermocouples and extension wires are available in J, K, T, and E types and follow ANSI color coding specifications.

SC-2311, SC-2345, and CA-1000 Series connector panelettes. Thermocouple  miniconnector plugs come in quantities of 10, and are available for J, K, T, and E types. 

## **RTDs** 

## **Field-Cuttable Thermocouples** 

NI field-cuttable thermocouples suit a wide variety of temperature applications. With field-cuttable thermocouples, you can cut the metal sheathed probe to the desired length – from 8.9 to 61 cm (3.5 to 24 in.) 

RTDs are popular for high-accuracy temperature measurement applications. NI offers 3-wire, 100 Ω platinum RTDs that conform to the DIN 43760-1980 (European) standard curve (a = 0.00385). These RTDs are available as field-cuttable metal sheathed probes and ready-made element configurations. 

## **Ready-Made Thermocouples** 

For cost-sensitive applications, NI offers ready-made thermocouples – individual packets of thermocouple wire with the measuring junction provided at one end. Ready-made thermocouples are ideal for starter or educational applications. 

## **Field-Cuttable RTDs** 

NI field-cuttable RTDs are ideal for a wide variety of temperature applications. With field-cuttable RTDs, you can cut the metal sheathed probe to the desired length – from 8.9 to 61 cm (3.5  to 24 in.). 

## **Ready-Made RTDs** 

## **Thermocouple and Extension Wire** 

For large-scale or custom temperature measurement applications, NI offers spools of thermocouple and extension wire. You are responsible for making the thermocouple junction. 

Ready-made RTDs offer solutions for cost-sensitive temperature measurement applications. Each RTD element is sealed in an Alumina tube, with three Teflon-coated leads, and can measure up to 204 °C (400 °F).
