SI-131 Ultra-Narrow Field of View Infrared Radiometer Sensor 14º APOGEE

Approximate Sensitivity: 20 μV per C

Output from Thermistor: 0 to 2500 mV (typical, depends on input voltage)

Input Voltage Requirement: 2500 mV excitation (typical, other voltages can be used)

Calibration Uncertainty (-20 to 65 C): 0.3 C, when target and detector temperature are within 20 C

Calibration Uncertainty (-40 to 80 C): 0.5 C, when target and detector temperature are different by more than 20 C

Measurement Repeatability: < 0.05 C

Stability (Long-term Drift): less than 2 % change in slope per year when germanium filter is maintained in a clean condition

Response Time: 0.2 s

Field of View: 14° half angle

Spectral Range: 8 to 14 μm; atmospheric window

Operating Environment: -55 to 80 C, 0 to 100 % relative humidity (non-condensing)
