AI Technical Summary
Existing gas sensors lack external protection, are easily damaged, and lead to increased operating costs.
A protective device comprising a venting mechanism and a sealing mechanism is designed. The venting mechanism is detachably installed through one end of a transparent tube, and the sealing mechanism is detachably installed through the other end of a transparent tube. The venting mechanism consists of a water-permeable component, a pressure ring, a waterproof and breathable membrane, a perforated plate, and a connector. The sealing mechanism consists of a plug, a fixing block, a connecting column, and a sealing sleeve, which are used for gas transmission and cable sealing, respectively.
It effectively prevents external impurities from entering the transparent tube, protecting the gas sensor, extending its service life, and providing protection and easy observation for the gas sensor.
