ZTP-148SR Thermopile IR Sensor Thermometrics Thermopile IR Sensors are used for non-contact surface, or infrared, temperature measurement. The ZTP-148SR Model consists of thermo-elements, flat infrared filter and thermistor for temperature compensation, all in one hermetically-sealed TO-46 (18) sensor package. There are a variety of filters available to maximize performance in specific applications. Applications Features • Ear thermometers • Compact design • Forehead thermometers • High sensitivity • Surface temperature measurement of the human body • Fast response time • Low cost • Included ambient temperature (thermistor) sensor Amphenol Advanced Sensors ZTP-148SR Specifications Thermopile Chip Limits Parameter Min Typ Chip Size Active Area Internal Resistance 60 2 mm 1.0×1.0 mm Absorber area 111 kΩ @25°C 0.12 %/°C 85 43 2 61 Responsivity T.C.
