TPS 434 - Thermopile Detector Extremely Small Absorber Size
Description
The TPS 434 thermopile sensor in TO 5 te housing employs a chip of 0.5 x 0.5 mm2 absorber size and a
30 k thermistor as temperature reference. The round window opening is equipped with a 5.5 mm longp
(standard) infrared filter. The sensor shows a flat sensitivity characteristic over the wavelength.
The TPS 434 can be equipped with a G9 (8 ... 14 m) filter for precision pyrometers (TPS 434 G9).
Features
Extremely Small Absorber Size - for High Precision Pyrometers
Thermistor Temperature Reference included
Low Temperature Coefficient of Sensitivity
Applications: Ear Thermometers and Pyrometers
