Abstract

The invention relates to a fluorescence sensor for gas detection. The fluorescence sensor comprises a base unit. A glass holding slot is formed in the middle of the base unit, a glass sheet is arranged in the glass holding slot, a fluorescence material cell is formed in the middle of the bottom of the glass holding slot and is filled with a fluorescence material, cotton holding holes are symmetrically formed in the left side and the right side of the fluorescence material cell and filled with cotton, the fluorescence material cell is disposed in the center of the base unit, a vent hole runningthrough the base unit is formed from left to right of the middle of the base unit, the fluorescence material cell and the cotton holding holes are communicated through the vent hole, and hoses are inserted at the left end and the right end of the vent hole respectively. The fluorescence sensor is small in size, high in air-tightness, simple in manufacturing process, low in cost, and is reusable.

Description

technical field [0001] The invention relates to a fluorescent sensor for gas detection. Background technique [0002] A gas detection sensor is a device that converts information such as gas composition, concentration, or volume fraction into information that can be used by personnel, instruments, and computers. Gas sensors mainly include: semiconductor gas sensors, catalytic combustion gas sensors, thermal conductivity cell gas sensors, electrochemical gas sensors, infrared gas sensors, etc. Among these commonly used gas sensors, the semiconductor gas sensor is cheap, but its stability is poor, it is easily affected by the environment, and it is not suitable for use in places where accurate measurement is required; although the catalytic combustion gas sensor has accurate measurement, fast response and long life, but It can only be used for flammable gas detection; the thermal conductivity cell gas sensor has a narrow application range and many limiting factors; although t...
