Industrial catalog RTDs and thermocouples

Measurement and control products that are safe, reliable, effective and sustainable

Resistance temperature detectors (RTDs) are sensors that measure temperature by correlating the resistance of the RTD element with temperature. Thermocouples consist of two dissimilar metals joined at one end. Cooling or heating the junction of the two metals produces a voltage that correlates to temperature. Most thermocouple alloys are commonly available as wire.
