Temperature sensing devices provide temperature measurement and signals for monitoring or control. The most common sensing methods include thermocouples and resistance temperature devices (RTD).

  • Thermocouples consist of two dissimilar metal wires joined at a hot junction, generating millivolt signals as temperature changes
  • RTDs and thermistors measure the change in resistance as the temperature of the sensing element varies
  • Temperature transmitters convert millivolt input signals from thermocouples or RTDs to analog outputs compatible with industrial monitoring or control devices; select transmitters also support temperature data transmission using IO-Link and HART communication protocols.
  • Temperature switches open or close switch contacts when a preset temperature is reached, and provide simple setpoint-tripped outputs for alarming, set and reset hysteresis, and simple temperature control
  • Infrared pyrometers allow non-contact sensing by determining the surface temperature of an object based on its emitted infrared radiation, preventing sensor contamination or exposure to hazardous materials
  • Thermowells allow thermometers or spring-loaded RTD and thermocouple probes to be inserted and removed without interrupting the process and eliminate the need for a separate probe mounting fitting or adapter

Temperature Sensors

Temperature Sensors

Temperature sensors vary the voltage or resistance in a circuit relative to the temperature of its surroundings. Common sensor types are thermocouples, RTDs, and thermistors. Thermocouples generate a millivolt signal, while RTDs and thermistors use resistance values to represent the measured temperature. A wide range of probe and installation styles are available.
