THERMOPILE INFRARED SENSOR
▓ Features
The thermopile sensor consists of a series of 44 thermoelements, forming a
sensitive area of 0.5 x 0.5 mm2. The sensor is hermetically sealed into a TO-5
metal housing, with optical filter. This filter allows measurements to be made
in the spectral range above 8 µm 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
thermistor on the same package.
The standard version of thermistor is
housing connected to ground.
▓ Applications
