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

Structural principle
By measuring system (including joints, corrugated box, etc.), transmission mechanism (including rod mechanism, gear transmission mechanism), indicating parts (including pointer and dial) and shell (including case, ring and table glass). The working principle of the diaphragm pressure gauge is based on the corrugated diaphragm box under the pressure of the measured medium, its free end produces the corresponding elastic deformation, and then through the transmission of a gear drive mechanism and amplified, the measured value is indicated on the dial by the pointer fixed on the gear shaft.
