RTD Sensors

RTD Sensors

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...

Temperature Sensors

Temperature Sensors

Temperature sensors are devices that detect and measure coolness and hotness and convert it into an electrical signal. Temperature sensors are utilized in our daily lives, be it in the form of domestic water heaters...

Thermistors

Thermistors

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...

Thermocouples

Thermocouples

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...
