Structural features of the mask differential pressure tester

Structural features of the mask differential pressure tester.

 

1、Using a vacuum pump to achieve the power source for the test product;

 

2, the use of fixtures to achieve the internal and external pressure measurement of the product, built-in differential pressure sensor;

 

3、The chassis is in the form of an integrated machine with built-in vacuum pump and digital display meter to achieve automatic detection of pressure and automatic display.

 

Test principle of the mask differential pressure tester.

 

The tester is mainly used to measure the pressure difference between the two sides of the mask for gas exchange, using a differential pressure sensor to detect the differential pressure value; the flow rate is controlled through a regulating valve. The automatic control system consists of a panel control system, flow rate adjustment system, differential pressure detection system, alarm system, etc. The controls chosen are highly reliable, which can reduce the failure rate of the instrument and improve the test efficiency.     https://www.qinsun-lab.com/News-and-events/2046.html
