Thermopile Infrared Detectors
Thermopile Detector
Small absorber size 聳 best suited for temperature
measurement applications
Standard type for pyrometers and ear thermometers
The
TPS 334
thermopile sensor in TO 5 type housing employs a chip of
0.7 x 0.7 mm
2
absorber size and a 30聽kV thermistor as temperature reference.
The round window opening is equipped with a 5.5聽
m
m longpass (standard)
infrared filter. The sensor shows a flat sensitivity characteristics over the
wavelength.
The TPS 334 can be equipped with a G9 (8..14聽
m
m) filter for precision remote
temperature sensing (TPS 334 G9).
