ZTP-135BS Thermometrics Thermopile IR Sensor This thermopile sensor is used for non-contact surface Features temperature measuring. The ZTP-135BS model consists of thermo-elements, a flat IR filter, and a thermistor for Small-size sensor (TO-46 package) temperature compensation in a hermetically-sealed TO-46 (18) package. There is also a variety of filters available to help maximize performance in specific Included ambient temperature (thermistor) applications. sensor for compensation Fast response time Applications Low cost Industrial IR thermometer High sensitivity Ear thermometers Non-contact thermometers Amphenol Advanced SensorsSpecifications Thermopile Chip Thermistor Resistance (R-T Table) Parameter Limits Units Condition Tamb (C) Rmin (k Rcent (k) Rmax (k) Min Typ Max -20 893.6 931.5 970.3 2 Chip Size 1.8 x 1.8 mm -15 677.5 705.3 733.6 2 Diaphragm Size 1.4 x 1.4 mm -10 518.0 538.5 559.4 2 Active Area 0.7 x 0.7 mm -5 399.2 414.5 430.0 Internal Resistance 42 60 78 k 25 C 0 310.1 321.5 333.1 Resistance T.C. 0.12 %./ C 5 242.5 251.2 259.9 Responsivity 38 54 70 V/W 500K, 1Hz 10 191.0 197.6 204.2 15 151.5 156.5 161.6 Responsivity T.C. -0.03 %./ C Noise Voltage 32 nV rms R.M.S., 25 C 20 120.8 124.7 128.6 1/2 NEP 0.59 nW/Hz 500K, 1Hz 25 97.00 100.0 103.0 1/2 Detectivity 1.18 E08 cmHz /W 500K, 1Hz 30 78.14 80.65 83.15 Time Constant 25 ms 35 63.30 65.40 67.50 40 51.56 53.32 55.09 45 42.21 43.69 45.19 Thermistor 50 34.72 35.98 37.25 55 28.70 29.77 30.85 Parameter Limits Units Condition 60 23.83 24.74 25.66 Min Typ Max 65 19.88 20.66 21.44 Resistance 97 100 103 k Tol.:3%, 25 C 70 16.65 17.32 17.99 Beta - Value 3901 3940 3979 K Tol.:1%, Defined at 75 14.00 14.58 15.16 25 C/50 C 80 11.82 12.32 12.82 85 10.022 10.45 10.88 Absolute Maximum Ratings 90 8.526 8.896 9.275 95 7.278 7.601 7.930 Operating Temperature 100 6.235 6.516 6.804 -20C ~ 100C Storage Temperature -40C ~ 120C
