TP337
TP337 is Thermopile Infrared Sensor manufactured by Unknown Manufacturer.
Features
The thermopile sensor consists of a series of 116 thermoelements, forming a sensitive region size of 545m (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 5 m wavelength. The thermosensor exhibits an almost white noise, parable 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.
