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 is a Common Use for Resistance Thermometry Bridges?

A resistance thermometry bridge, or precision thermometer, is commonly found in laboratories to measure the resistance of a material to indicate temperature.
