TP339UG

THERMOPILE ▓ Features Part No: Type: 80-01-00008 TP339UG The thermopile sensor consists of a series of 116 thermoelements, forming a sensitive region size of 900*900μm2 .The sensor is hermetically sealed into a TO-18 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. 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. ▓ 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 OPTO TECH CORPORATION OPTO TECH Microelectronics Business Division Since 1983 2003.01 1 / 16 Tel: 886-3-5638951 Fax: 886-3-5783696 http://www.opto.com.tw THERMOPILE Part No: Type: 80-01-00008 TP339UG ▓ Electrical Characteristics Parameter Thermopile Condition Min.
