OPTO TECH CORPORATION TP337A Datasheet
THERMOPILE
Part No : 80-02-00013
▓
Features
Type : TP337A
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 5
m 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.
