The crystal absorption fiber temperature sensor utilizes the characteristics of the absorption spectrum of the gallium arsenide wafer as a function of temperature to achieve real-time temperature measurement. The product has the characteristics of no electromagnetic interference, transient response, accurate temperature measurement, etc. It can be widely used in oil fields, oil depots, power systems, large granaries, chemicals, printing and dyeing, etc. It is flammable, explosive and cannot be measured by conventional electric measurement methods. The temperature monitoring site effectively solves the real-time temperature monitoring problem under complex and special environmental conditions.
The expert appraisal committee believes that the crystal absorption optical fiber temperature sensor successfully developed based on the spectral absorption characteristics of gallium arsenide crystal has high measurement accuracy and fast response time. The project adopts optical fiber splitting technology, which reduces the requirement for light source stability. The sensor is more practical and stable; the sensor uses a miniature fiber collimator to effectively reduce the volume of the temperature probe.
