TP336

Thermopile Infrared Sensor ▓ Features TP336 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 5µm 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. www.DataSheet4U.com ▓ Applications * Ear thermometers; clinic thermometers * Infrared 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 Microelectronics Dept. 2000.05 1/8 Thermopile Infrared Sensor ▓ Electrical Characteristics TP336 Parameter Thermopile Number of thermojunctions www.DataSheet4U.com Condition Min.
