RTD (PT100) probes

RTD & PT100 temperature probes. Resistance Temperature Detectors (RTDs) offer excellent accuracy over a wide temperature range. Sensors are interchangeable between different manufacturers, and are available in various accuracy ratings and packages to suit most applications. Unlike thermocouples, it is not necessary to use special cables to connect to the sensor. Tolerance Specification for all ETI manufactured RTD/PT100 probes is displayed on the relevant probe's page. Click here to read our RTD/PT100 probe guide!

RTD/PT100 Temperature Probe Guide

ETI manufactures an extensive range of PT100 (RTD) probes to compliment our range of portable, hand held thermometers and data-loggers. Resistance temperature detector probes are slower to respond to changes in temperature than thermocouple probes, but are generally more accurate. 

Resistance temperature detectors
Resistance temperature detector (PT100 or RTD) probes consist of flat film or a wire wound platinum resistance sensor element. The measurement resistance value changes in line with the temperature being measured.

lead types
PVC leads are general purpose leads and available in lengths up to 100 metres. The stainless steel braided lead is a high temperature (fibreglass insulated) lead with a maximum temperature of 350 °C. As standard and where appropriate, each probe is supplied with a one metre straight PVC lead and a connector. Maximum temperature for both PVC and PU leads is 80 °C.

applications
Applications quoted are typical for the specific probe, although there are many alternative uses for which the probe could be equally suitable. For advice on a specific probe for a particular application, please contact the ETI technical sales team. Where requirements cannot be met from the existing standard range of probes, alternative designs can be manufactured.
