Alternating Pressure Tester

Alternating Pressure Tester

The alternating pressure testing machine performs repeated pressure increase and decrease simulation loading on the pressure instrument within the working pressure range to detect whether the product meets the service life. It is suitable for pressure alternation (aging, aging) testing of pointer pressure gauges, pressure sensors, differential pressure sensor products, spring tubes, and pressure sensitive components. It is designed and manufactured in accordance with relevant national and industry standards. It is widely used in production inspection and development research of various pressure instruments in pressure instrument production factories, product quality inspection institutes, scientific research institutions and other units.
