ZTP-115 Thermopile IR Sensor This thermopile sensor is used for non-contact Features surface temperature measuring. The ZTP-115 model consists of thermo-elements, flat IR filter, Non-contact measurement a thermistor for temperature compensation and a hermetically-sealed small-size package. There Wider surface area measurement is also a variety of filters available to maximize performance in specific applications Small-size sensor package Applications Included ambient temperature (thermistor) sensor for compensation Patient monitoring High sensitivity Ear & Tympanic thermometers Fast response time Occupancy detection Low cost HVAC RoHS compliant Appliance Amphenol Advanced SensorsSpecifications Thermopile Chip Thermistor Resistance (R-T Table) Parameter Limits Units Condition T ambient ( C) Rmin (kW) Rcent (kW) Rmax (kW) -40 267 284.7 303.2 Min Typ Max -35 197.2 209.6 222.5 2 Chip Size 1.8 x 1.8 mm -30 147.1 155.9 165 2 Diaphragm Size 1.0 x 1.0 mm -25 110.8 117.1 123.6 2 Active Area 0.5 x 0.5 mm -20 84.16 88.68 93.35 Internal 35 50 65 kW 25C -15 64.46 67.73 71.11 Resistance -10 49.74 52.13 54.59 Resistance T.C 0.15 %/C -5 38.65 40.41 42.21 Responsivity 42 60 78 V/W 500K, 1 Hz 0 30.24 31.54 32.86 Responsivity T.C -0.10 %/C 5 23.81 24.77 25.75 Noise Voltage 30 nV rms R.M.S., 25C 10 18.86 19.58 20.3 1/2 NEP 0.50 nW/Hz 500K, 1 Hz 1/2 15 15.03 15.56 16.1 Detectivity 1.00 E08 cmHz /W 500K, 1 Hz 20 12.04 12.44 12.84 Time Constant 20 ms 25 9.7 10 10.3 30 7.823 8.082 8.342 35 6.342 6.566 6.791 40 5.168 5.361 5.557 45 4.233 4.4 4.569 Thermistor for Temperature 50 3.484 3.629 3.776 Compensation 55 2.882 3.007 3.135 60 2.396 2.504 2.615 Parameter Limits Units Condition 65 2.0009 2.095 2.192 Min Typ Max 70 1.679 1.7612 1.8458 Resistance 9.7 10 10.3 kW Tol. :3%, 25C 75 1.4153 1.4871 1.5612 Beta - Value 3930 3970 4010 K Tol. :1%, Defined at 80 1.1984 1.261 1.3264 25C/85C 85 1.0193 1.0745 1.1317 90 0.8707 0.9193 0.9697 Absolute Maximum Ratings 95 0.7469 0.7898 0.8344 100 0.6433 0.6812 0.7208 Operating Temperature 105 0.5562 0.5899 0.625 -20C ~ 100C Storage Temperature -40C ~ 120C
