TP337 Infrared Thermopile Sensor
Features :
The thermopile sensor consists of a series of 116 thermoelements, forming a sensitive regionsize of 545m (diameter). The sensor is hermetically sealed into a TO-5 metal housing, with anoptical filter. This standard filter allows measurements to be made in the spectral range above 5m 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. The thermopile sensors are featured with an additional temperature reference resistor on the same chip. The standard version of temperature reference resistor is housing connected to ground.
