Thermopile Infrared Detectors
Thermopile Detector
Large absorber size 聳 high signal output
Thermistor temperature reference included
Low temperature coefficient of sensitivity
Applications: ear thermometer, gas detectors (with
additional infrared bandpass filter)
The
TPS 535
thermopile sensor in TO 5 type housing employs a chip of 1.2 x 1.2
mm
2
absorber size and a 30聽kV thermistor as temperature reference. The square
window opening is equipped with a 5.5聽mm longpass (standard) infrared filter.
The sensor shows a flat sensitivity characteristics over the wavelength.
The
TPS 535
can also be equipped with infrared bandpass filters for NDIR gas
detection.
