1、 Product Introduction:

An airtight detection sensor is a type of detection device that can be controlled to form a control alarm system or a dedicated detection device. For example, a combination of an air tightness tester and specialized fixtures can be used to create a specialized machine tool for detecting the air tightness performance of workpieces in a production line. Common leak testing machines for motorcycles and cars include cylinder head leak testing machines, clutch cover (or assembly) leak testing machines, cylinder inspection leak testing machines, transmission housing leak testing machines, and other specialized leak testing machines for motorcycles and cars. Widely used for testing in industries such as machinery, electronics, medical equipment, air conditioners, gas appliances, etc., to improve product quality, efficiency, low consumption, achieve economies of scale expansion and internationalization.

The operation process of the differential pressure type airtight detection sensor is to use a "standard sample" as a reference to compare the differential pressure changes between the measured workpiece and the "standard sample" under the same process and state conditions to determine whether the measured workpiece is qualified.

The detection process is as follows:

It can be used to purify dry air as a working medium for testing the sealing performance of chambers with a certain content volume, and other tests can also be conducted in series or parallel. But it is not allowed to directly detect gas-liquid two-phase flow systems and gas-solid two-phase flow systems, otherwise incorrect measurements may be obtained

Test results or irreparable damage to the instrument.

Firstly, connect the standard sample to the reference end of the airtight sensor, and then simultaneously inflate the standard sample and the measured workpiece chamber (inflation pressure, time and other parameters are determined by the process). After the pressure is balanced, completely isolate the standard sample from the measured chamber of the workpiece for several seconds or tens of seconds of pressure monitoring, and compare the pressure readings of the two. This pressure difference is the pressure leakage value of the measured chamber of the workpiece. If its value is within the allowable range, it is considered that the measured sample is qualified, otherwise it is judged as unqualified.
