AI Technical Summary

Problems solved by technology

There are visual blind spots in video surveillance and it is difficult to judge leaks. Manual inspections also cannot find chemical leaks in a timely and effective manner, and the labor intensity is high.
Therefore, there are no very mature products or effective solutions for this kind of dangerous liquid leakage detection at home and abroad.

Abstract

The invention provides a sensor for detecting leakage of liquid chemicals. The sensor is composed of a matrix, a membrane body and an induction element, wherein the matrix is of a cavity structure and is provided with a hole; the membrane body is placed in the cavity and covers and seals the hole in the matrix; the induction element is placed in the sealed cavity and provided with a cable; and the cable penetrates the matrix and is led out. The sensor provided by the invention is small in size and easy to install and arrange and can quickly detect leaked liquid; and due to the enclosed cavity structure, the sensor has good environment adaptability and is not prone to sounding of false alarms.

Description

technical field [0001] The invention relates to a sensor for detecting leakage of liquid chemicals and belongs to the technical field of sensors. Background technique [0002] Chemical liquids are prone to sudden leakage accidents during storage, packaging, and use, and dangerous chemicals can easily cause environmental pollution after leakage, and even cause major safety accidents such as fire and explosion. Therefore, if the leakage of dangerous chemical liquid can be sensed in time, it can be dealt with in time to avoid major accidents. At present, the monitoring of dangerous liquid chemicals generally adopts the method of video remote monitoring or manual inspection. There are visual blind spots in video surveillance and it is difficult to judge leakage. Manual inspection also cannot find chemical leakage in a timely and effective manner, and it is labor-intensive. Therefore, there are no very mature products or effective solutions for the detection of such dangerous l...
