Thermopile Infrared Sensor
▓ Features
TP336
The thermopile sensor consists of a series of 116 thermoelements, forming a sensitive region size of 545µm (diameter). The sensor is hermetically sealed into a TO-5 metal housing, with an optical filter. This standard filter allows measurements to be made in the spectral range above 5µm wavelength. The thermosensor exhibits an almost white noise, comparable to an ohmic resistance. It has a constant signal versus frequency up to its frequency limit, and is directly proportional to incident radiation.
