ZTP-115

GE Measurement & Control ZTP-115 Thermopile IR Sensor This thermopile sensor is used for non-contact surface temperature measuring. The ZTP-115 model consists of thermo-elements, 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 Patient monitoring Ear & Tympanic thermometers Occupancy detection HVAC Appliance 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 RoHS compliant Specifications Thermopile Chip Parameter Limits Min Typ Chip Size Diaphragm Size Active Area Internal Resistance Resistance T.C Responsivity Responsivity T.C Noise Voltage NEP Detectivity Time Constant 35 42 1.8 x 1.8 1.0 x 1.0 0.5 x 0.5 50 60 -0.10 30 0.50 1.00 E08 20 Units Condition Max mm2 mm2 mm2 65 kW 25°C 0.15 %/°C 78 V/W 500K, 1 Hz %/°C nV rms R.M.S., 25°C nW/Hz1/2 500K, 1 Hz cmHz1/2/W 500K, 1 Hz ms Thermistor for Temperature Compensation Parameter Limits Units Condition Min Typ Max Resistance Beta - Value 9.7 3930 10 3970 10.3 4010 kW Tol. :3%, @25°C K Tol. :1%, Defined at 25°C/85°C Absolute Maximum Ratings Operating Temperature -20°C ~ 100°C Storage Temperature -40°C ~ 120°C Thermistor Resistance (R-T Table) T ambient (° C) ...
