Resistance thermometry bridges

Highly accurate resistance thermometry bridges from WIKA

By using built-in or external standard resistors, resistance thermometry bridges measure resistance ratios with high accuracy, which are indicative of the temperature, among other things. These instruments are not only used in the field of temperature measurement, but − due to their high accuracy − also in electrical laboratories.

What do different abbreviations like RTD, PRT, SPRT… mean?

RTD (Resistance Temperature Detector) – a temperature sensor whose resistance changes with temperature
PRT (Platinum Resistance Thermometer) – RTD using platinum wire for the resistance element
Pt1000 – PRT with 1,000 Ohm at 0 °C.
Pt500 – PRT with 500 O ... More ...

What is a SMART probe?

The "SMART probe" is a precision RTD sensor with an electronic memory in its coupler connector. This memory chip stores the coefficients of the calibrated sensor and a complete history of the probe. This history includes the maximum and minim ...
