Expansion device for pressure gauge calibration

The pressure medium of the multi interface pressure gauge calibrator is oil, purified water or air. Adopting independently developed pressurization device and transparent open structure, the system cleaning is very convenient. It has a simple structure, high reliability, easy operation and maintenance, and is not easy to leak. The booster device adopts the spiral pressure pump developed by our company through years of practical experience (the booster piston does not rotate, has low friction, uses special sealing materials, and has a long service life). It has a large pressure adjustment range and smooth pressure rise and fall, overcoming the problems of inability to return to zero and inability to meet the calibration requirements during the pressure reduction process when using a globe valve for high-pressure check. It can provide easily adjustable and stable high pressure. Due to its open and transparent structure, users often overlook the convenience of maintenance and upkeep when selecting models.

The price of a multi interface pressure gauge calibrator is an auxiliary equipment for calibrating pressure (differential pressure) transmitters, precision pressure gauges, ordinary pressure gauges, pressure switches, and other instruments. It is used in conjunction with pressure standards to complete detection and calibration work. The main features of this series of products are: simple structure, stable pressure generation, and effortless operation.
