Sandelius Instruments is a premier manufacturer of thermocouple assemblies, thermocouples, RTDs, temperature sensors and RTD sensors. Since 1956, we have provided reliability and quality you can trust, along with the design expertise to meet all your temperature measurement needs.
An RTD, resistance temperature detector, is a passive temperature sensing device that operates on the principle that the resistance of a metal changes as the temperature changes. The electrical current that passes through the element...
A thermistor, a shortened version of the term thermal resistor, is a passive component whose resistance changes as the temperature in a system changes. Thus they serve as an inexpensive, accurate, and dynamic method for measuring temperature...
A thermocouple is a transducer that converts thermal energy into electrical energy and is constructed by joining wires made from dissimilar metals to form a junction. Voltage is produced when the temperature at the junction changes...
