Thermopile Infrared Sensor
TP337
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, 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
www.DataSheet4U.cormesistor is housing connected to ground.
Applications
* Ear thermometers; clinic thermometers

* Consumer applications: hair dryer, micro-wave oven, air conditioner, refrigerator
* Continuous temperature control of manufacturing
* Security system
* Radiation monitor switch system
* Absorbing measurement for gas analysis
* Thermoelectric converter
* Heat flux flowmeter

Thermistor vs. temperature
The resistance of the temperature reference resistor varies with temperature and the behaviour is
illustrated in the following figure.
