YE-100, 150 pressure gauges with diaphragm box are suitable for measuring the micro-pressure and negative pressure which have no corrosion effect on copper alloy and no explosion danger. Gas is widely used in boiler ventilation and gas piping equipment. Pressure gauges with diaphragm case can be installed on site and indicated on site.

Structure principle
By measuring system (including joint, corrugated diaphragm box, etc.), transmission mechanism (including pulling rod mechanism, gear transmission mechanism), indicating parts (including pointer and dial) and shell (including watchcase, lining ring and table glass). The working principle of pressure gauge of diaphragm box is based on the elastic deformation of the free end of the corrugated diaphragm box under the pressure of the measured medium, and then the transmission and amplification of the pulling rod and gear drive mechanism, and the pointer fixed on the gear shaft will be measured on the dial indicated.
