The TE Connectivity TS3xx thermopiles are unique temperature sensors able to measure a wide range of surface temperatures without making physical contact to the object of interest. The sensor consists of a chip having an array of micro-thermocouple elements, a reference ambient temperature sensor, an infrared filter window, all contained in a hermetically sealed metal enclosure. The sensor provides a voltage output that is proportional to the thermal infrared energy entering the sensor through the filter window.
