GE Measurement & Control ZTP-315 Thermometrics Thermopile IR Sensor The ZTP-315 thermopile IR sensor is used for noncontact surface temperature monitoring. The ZTP315 model consists of thermoelements, a flat IR filter, a thermistor for temperature compensation and a hermetically-sealed small-size package. There is also a variety of filters available to maximize performance in specific applications. Applications • HVAC • Occupancy detection • Automotive Features • Non-contact measurement • Wider surface area measurement • Small-size sensor 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 Tamb (°C) Rmin (kΩ Rcent (kΩ) Rmax (kΩ) -40 847.1 885.1 924.7 2 Max Chip Size 3.6 x 3.6 mm -35 624.1 650.2 677.2 Diaphragm Size 2.6 x 2.6 mm2 -30 464.0 481.9 500.5 Active Area 1.3 x 1.3 mm2 -25 348.0 360.3 373.1 -20 263.1 271.7 280.5 -15 200,6 206.5 212.7 -10 154.1 158.3 162.5 -5 119.3 122.2 125.2 Internal Resistance 35 50 22 32 Resistance T.C.
