Thermopile Sensors are used for measuring non-contact surface temperatures. The ZTP-101T type is made up of thermo-elements, a flat Infrared (IR) filter, a thermistor for temperature correction, and a hermetically sealed small-size package. There are also other filters available to optimize performance in specific applications.
