  • What are Thermocouples?

    Simply put, this device is used for measuring temperature. The device's functions are made possible by joining materials that have different Setback coefficients.
  • RTD, Thermocouple, and Thermistor

    For certain industries and functions, having exact temperature measurements is an absolute must. The temperature gauges must be able to read small changes in temperature.


A thermocouple is made of two connected, but dissimilar, metal wires that produce an electronic potential directly related to a change in temperature. These changes in voltage are predictable and repeatable in relationship to the temperature. Thermocouples have a wide range in temperature but aren’t as accurate as RTDs or thermistors.
