Description

Sanitary waterproof chuck type sensor shell Technical Field The utility model relates to the technical field of sensor protection equipment, in particular to a sanitary waterproof chuck type sensor shell. Background The sensor is a detection device which can sense the measured information and convert the sensed information into an electric signal or other information output in a required form according to a certain rule so as to meet the requirements of information transmission, processing, storage, display, recording, control and the like. In the ultraviolet water treatment industry, a UV sensor is a core monitoring component for ensuring the water treatment effect, the accurate monitoring of the ultraviolet intensity is critical to water quality purification, however, the working environment of the industry is extremely complex, water, chemical agents and ultraviolet irradiation exist for a long time, the existing sensor shell is difficult to adapt to the environment, and the ultraviolet water treatment ultraviolet radiation ultraviolet sensor has the defects that firstly, the shell made of common materials is easily affected by chemical erosion and ultraviolet aging, so that the protective performance is reduced, the service life is shortened, secondly, the traditional connecting and sealing structure is easy to loose and fail in sealing after long-term use, so that water and chemical substances infiltrate, damage the UV sensor and further interfere with the normal operation of a water treatment system, thirdly, the installation mode of most shells is complex, the difficulty and the cost of installation and maintenance are increased, and the requirement of high-efficiency operation and maintenance of the industry is difficult to meet. Therefore, it is urgent to develop a sensor housing which can be adapted to the special environment of the ultraviolet water treatment industry, is convenient to install and has excellent protection performance. Disclosure of utility model The utility model aims to solve the problems of insufficient protective performance and inconvenient installation of a sensor housing in the ultraviolet water treatment industry in the prior art, and provides a sanitary waterproof chuck type sensor housing.
