TPS 334 - Thermopile Detector Small Absorber Size Description Features The TPS 334 thermopile sensor in TO 5 type housing employs a chip of 0.7 x 0.7 mm2 absorber size and a 30 k thermistor as a temperature reference. The round window opening is equipped with a 5.5 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 m) filter for precision remote temperature sensing (TPS 334 G9). * Small Absorber Size - Best Suited for Temperature Measurement Applications * Standard Size for Pyrometers and Ear Thermometers TPS 334 - Thermopile Detector Small Absorber Size Figure 1.
