ZTP-135SR Thermometrics Thermopile IR Sensor This thermopile sensor is used for non-contact Features surface temperature measuring. The ZTP-135SR model consists of thermo-elements, flat IR filter, Small-size sensor (TO-46 package) a thermistor for temperature compensation in a hermetically-sealed TO-46(18) package. There is Included ambient temperature (thermistor) also a variety of filters available to help maximize sensor for compensation performance in specific applications.
