Industrial Process Temperature Sensors, Thermocouples and RTD Assemblies

Industrial process temperature sensors, thermocouples and RTD assemblies are critical components used to monitor and control temperature in demanding industrial applications. High temperature thermocouples and RTD sensors provide accurate thermal feedback for process control, equipment protection, energy efficiency and product quality across a wide range of industries.

What Are Industrial Thermocouples?

Thermocouples are temperature sensors manufactured by joining two dissimilar metal conductors together at a sensing junction. When heated, the junction generates a millivolt signal proportional to temperature. Industrial thermocouple assemblies are valued for their fast response time, wide temperature range, durability and vibration resistance.

What Are RTD Sensors?

RTD sensors, or Resistance Temperature Detectors, operate by measuring the resistance change of a precision platinum element as temperature changes. PT100 RTD assemblies are commonly used where higher accuracy, repeatability and long-term stability are required.

High Temperature Industrial Sensor Assemblies

High temperature industrial thermocouple and RTD assemblies are available in mineral insulated constructions with stainless steel, Inconel, ceramic or refractory metal protection sheaths for operation in harsh industrial environments. Common assembly styles include bayonet thermocouples, tube and wire assemblies, melt bolt thermocouples, nozzle sensors, ring sensors, immersion probes, threaded probes and custom industrial process assemblies.
