Profile: Thermo Sensors Corporation manufactures thermocouples, thermowells, RTD's, wire and thermosensor accessories. Industrial thermocouples are widely used in process industry applications. Thermowells are used to provide an isolation between a temperature sensor and the environment, either liquid, gas or slurry. It allows the temperature sensor to be removed and replaced without compromising either the ambient region or the process. Resistance temperature detectors (RTD's) are frequently used in the plastics industries.
