Description Features
The TPS 334 thermopile sensor in • Small Absorber Size - Best Suited
TO 5 type housing employs a chip of for Temperature Measurement
0.7 x 0.7 mm
2
absorber size and a Applications
30 kΩ thermistor as a temperature • Standard Size for Pyrometers and
reference. The round window opening Ear Thermometers
is equipped with a 5.5 µm 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 µm) filter for precision
remote temperature sensing
(TPS 334 G9).
