Contact thermocouples and RTDs are the most prevalent in temperature measurement applications.
Thermocouples consist of two wires of different metals/alloys soldered together at two points. They deliver an e.m.f. which is dependant on the temperature and material used.
Resistance Thermometer Detectors (RTDs) use the material's (platinum or nickel) change in resistance, to determine the temperature.
Over 50 new models of thermocouples and RTD sensors are now available in various sizes and configurations along with a complete line of accessories including various connectors, transmitters, and extension wire.
