Leak detector

Abstract

The invention belongs to the field of pressure detection, and relates to an air leakage detector used for detecting the air leakage of pipe walls of various pipe materials, cigarette paper and the like. The detector consists of a shell, a detection circuit board, a temperature self-compensating diffused silicon pressure sensor, a pressure nozzle, a quick connector, a power supply / output cable, a waterproof connector, a lead wire and a cover plate, and the detection circuit board and a temperature self-compensated diffused silicon pressure sensor. The pressure sensor is installed in the shell and connected by lead wires; one end of the pressure nozzle is connected to the pressure chamber of the temperature self-compensating diffused silicon pressure sensor, and the other end extends out of the shell to connect with the measured pressure source; the waterproof joint is installed on the shell , used to fix the power / output cable; the power / output cable is connected to the detection circuit board and the quick connector. The detector can quickly detect the leakage of gas and liquid in industrial production, and output a linear voltage signal. It has the characteristics of high sensitivity, high detection accuracy, light weight, corrosion resistance, reliable performance, and convenient installation and use.

Description

technical field [0001] The invention belongs to the field of pressure detection, and relates to an air leakage detector used for detecting the air leakage of pipe walls of various pipe materials, cigarette paper and the like. Background technique [0002] In the process of industrial production, it is very necessary to test the air density of the pipe wall of various pipe materials, especially the detection of gas leakage in gas pipelines, which is even more important in relation to safety production issues. It plays a vital role in ensuring product quality by detecting the leakage of air in the air and removing defective products in time. But at present, there are problems of complex structure, slow detection speed and poor accuracy in the detection instruments for the air leakage of the pipe wall of various pipe materials, cigarette paper and the like. Contents of the invention [0003] The object of the present invention is to provide a gas leakage detector which can q...
