The TPS 333 is an extremely small thermopile detector employing a chip of 0.7 x 0.7 mm2 absorber size and a 100 kV thermistor as temperature reference.
The square window opening is equipped with a 5.5 mm longpass (standard) infrared filter. The detector shows a constant sensitivity characteristics over the wavelength.
• Miniature sensor housing: TO 18
• Thermistor temperature reference included
• Large signal; low temperature coefficient of sensitivity
• Ideally suited for ear thermometers, miniature pyrometers
