Crystal draws type fiber-optic temperature sensor passes achievement appraisal
From;  Author:Stand originally
Recently, committee of appraisal of expert of organization of branch department of Xi'an of the Chinese Academy of Sciences was passed " crystal draws type fiber-optic temperature sensor " project achievement appraisal. This project is accused by investment of place of smooth machine of Xi'an of the Chinese Academy of Sciences science and technology of flying second photoelectricity (Xi'an) limited company assumes development.

Crystal absorbs type to be measured of the characteristic implementation temperature that fiber-optic temperature sensor uses arsenic to change gallium chip to absorb spectrum to change along with temperature in real time. This product is had do not suffer electromagnetism interference, instantaneous is answered, measure lukewarm wait for a characteristic accurately, can apply extensively at system of oil field, oil depot, power, large barn, chemical industry, printing and dyeing to wait for a few places that explode combustibly, easily and cannot measure means to undertake temperature monitoring through groovy report, solved the problem of monitoring of real time temperature below complex, special ambient conditions effectively.

Expert appraisal committee thinks, the crystal that this project is based on arsenic to change gallium crystal to spectrum absorbs character and be developed successfully draws type fiber-optic temperature sensor, measure precision tall, answer time fast; The project uses fiber-optic and prismatic technology, reduced the demand to illuminant stability, make sensor more practical, stable; This sensor uses miniature fiber-optic collimation implement, reduced the volume that measures lukewarm probe effectively.
