Description
TP297A 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 * 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 ▓ Electrical Characteristics ROITHNER LASERTECHNIK Address : Schoenbrunner Str. 7, A-1040 Vienna, Austria Tel.
