ZTP-115 Thermopile Infrared (IR) Sensor Thermometrics Thermopile Infrared (IR) Features Sensors are used for non-contact surface temperature measurement. The ZTP-115 Model Non-contact measurement consists of thermo-elements, flat IR filter, and a thermistor for temperature compensation Wider surface area measurement in a hermetically-sealed small-size package. Various filters are also available to maximize Small-size sensor package performance in specific applications. Included ambient temperature (thermistor) sensor for compensation Applications Patient monitoring High sensitivity Ear & Tympanic thermometers Fast response time Occupancy detection Low cost RoHS compliant HVAC Appliance Amphenol Advanced SensorsSpecifications Thermopile Chip Thermistor Resistance (R-T Table) Limits T ambient Rmin (kW) Rcent (kW) Rmax (kW) Parameter Units Condition ( C) Min Typ Max -40 267 284.7 303.2 2 Chip Size 1.8 x 1.8 mm -35 197.2 209.6 222.5 Diaphragm 2 -30 147.1 155.9 165 1.0 x 1.0 mm Size -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 -0.10 %/C T.C 5 23.81 24.77 25.75 R.M.S., 10 18.86 19.58 20.3 Noise Voltage 30 nV rms 25C 15 15.03 15.56 16.1 1/2 NEP 0.50 nW/Hz 500K, 1 Hz 20 12.04 12.44 12.84 1/2 Detectivity 1.00 E08 cmHz /W 500K, 1 Hz 25 9.7 10 10.3 Time Constant 20 ms 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 Limits Parameter 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 80 1.1984 1.261 1.3264 at 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 Ordering Information Lead Length (mm) Part No. 3.0 ZTP-115 6.7 ZTP-115L1 13.2 ZTP-115L
