GE Measurement & Control ZTP-135SR Thermometrics Thermopile IR Sensor This thermopile sensor is used for non-contact surface temperature measuring. The ZTP-135SR model consists of thermo-elements, flat IR filter, a thermistor for temperature compensation in a hermetically-sealed TO-46(18) package. There is also a variety of filters available to help maximize performance in specific applications. Applications • Ear thermometers • Non-contact thermometers • Appliances • Electronics Features • Small-size sensor (TO-46 package) • Included ambient temperature (thermistor) sensor for compensation • High sensitivity • Fast response time • Low cost Thermopile Chip Thermistor Resistance (R-T Table) Parameter Limits Min Typ Units Condition Max Tamb (°C) Rmin (kΩ Rcent (kΩ) Rmax (kΩ) -20 909.1 947.9 987.3 1.8 x 1.8 mm2 -15 687.7 715.9 744.7 Diaphragm Size 1.4 x 1.4 mm 2 -10 524.5 545.4 566.5 Active Area 0.7 x 0.7 mm2 -5 403.3 418.8 434.5 25 °C 0 312.6 324.1 335.8 5 244.0 252.7 261.5 500K, 1Hz 10 191.8 198.5 205.1 15 151.9 156.9 162.0 Chip Size Internal Resistance 42 60 43 62 Resistance T.C.
