OTC-236

OTC-236 is thermopile infrared sensor .The thermopile sensor which forms a sensitive area of 0.5*0.5 mm2 consists of a series of 44 thermoelements . The sensor OTC-236 with an optical filter is hermetically sealed into a TO-5metal housing. This standard filter allows measurements to be made in the spectral range above 5 m wavelength. The thermosensor which is comparable to an ohmic resistanceexhibits an almost white noise . OTC-236 has a constant signal versus frequency up to its frequency limit,and is direct lyproportional to incident radiation.
There are eight essential applications of OTC-236.The first is that it has ear thermometers and clinic thermometers.The Second is it has infrared thermometers.The third is consumer applications,including hair dryer, micro-wave oven, air conditioner,and refrigerator.The forth is it has continuous temperature control of manufacturing. The fifth is it has security system.The sixth is it has Radiation monitor switch system
The seventh is it has Absorbing measurement for gas analysis.The eighth is it has thermoelectric converter.The ninth is it has heat flux flowmeter.
