The TPS 434 thermopile sensor in TO 5 type housing employs a chip of 0.5 x
0.5 mm² 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).
