Thermopile Infrared Detectors
Thermopile Detector
Extremely small absorber size for high precision
pyrometers
Thermistor temperature reference included
Low temperature coefficient of sensitivity
Applications: ear thermometers and pyrometers
The
TPS 434
thermopile sensor in TO 5 type housing employs a chip of 0.5 x
0.5 mm
2
absorber size and a 30 kV thermistor as temperature reference. The
round window opening is equipped with a 5.5 mm longpass (standard) infra-
red filter. The sensor shows a flat sensitivity characteristic over the wavelength.
The
TPS 434
can be equipped with a G9 (8...14 µm) filter for precision pyro-
meters ( TPS 434 G9).
