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 Features Applications • Included ambient temperature (thermistor) sensor for compensation • Patient monitoring • Ear & Tympanic thermometers • Occupancy detection • HVAC • Appliance • Non-contact measurement • Wider surface area measurement • Small-size sensor package • High sensitivity • Fast response time • Low cost • RoHS compliant Specifications Thermistor Resistance (R-T Table) Thermopile Chip Parameter Limits T ambient (° C) Rmin (kW) Rcent (kW) Rmax (kW) -40 267 284.7 303.2 -35 197.2 209.6 222.5 -30 147.1 155.9 165 -25 110.8 117.1 123.6 -20 84.16 88.68 93.35 -15 64.46 67.73 71.11 -10 49.74 52.13 54.59 -5 38.65 40.41 42.21 0 30.24 31.54 32.86 5 23.81 24.77 25.75 10 18.86 19.58 20.3 15 15.03 15.56 16.1 20 12.04 12.44 12.84 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 Tol. :3%, @25°C 50 3.484 3.629 3.776 Tol. :1%, Defined at 25°C/85°C 55 2.882 3.007 3.135 60 2.396 2.504 2.615 65 2.0009 2.095 2.192 Absolute Maximum Ratings 70 1.679 1.7612 1.8458 75 1.4153 1.4871 1.5612 Operating Temperature 80 1.1984 1.261 1.3264 -20°C ~ 100°C 85 1.0193 1.0745 1.1317 90 0.8707 0.9193 0.9697 Storage Temperature 95 0.7469 0.7898 0.8344 100 0.6433 0.6812 0.7208 105 0.5562 0.5899 0.625 Min Typ Units Chip Size 1.8 x 1.8 mm2 Diaphragm Size 1.0 x 1.0 mm2 Active Area 0.5 x 0.5 mm2 Internal Resistance 35 50 Resistance T.C 65 kW 0.15 Responsivity 42 60 Responsivity T.C 78 V/W nV rms 0.50 Detectivity 500K, 1 Hz %/°C 30 NEP 25°C %/°C -0.10 Noise Voltage Condition Max nW/Hz R.M.S., 25°C 1/2 500K, 1 Hz 1.00 E08 cmHz1/2/W 20 ms Time Constant 500K, 1 Hz Thermistor for Temperature Compensation Parameter Resistance Beta - Value -40°C ~ 120°C Limits Units Min Typ Max 9.7 10 10.3 3930 3970 4010 kW K Condition Field of View Sensitivity 6 Parameter 5 Typ Max 50 55 60 Field of View 4 Output[mV] Limits Min Units Condition Degree 50% of Maximum Output 3 2 1. 0 1 0. 9 0. 8 0 Normaliz ed O utput 0. 7 -1 -2 0 20 40 60 80 100 o o Object Temperature[ C] @Tamb.=25[ C] 0. 6 0. 5 0. 4 0. 3 0. 2 0. 1 0. 0 -60 -50 -40 -30 -20 -10 0 10 De gr ee Filter Transmission Data 100 T rans miss ion(%) 80 60 40 20 0 2 4 6 8 10 12 W avelength ( um) 14 16 18 20 20 30 40 50 60 Outline of Sensor Packaging and Pin Arrangement (unit: mm) Unit: mm Pin arrangement: 1.
