YP series diaphragm pressure gauges
”” Diaphragm seal pressure gauge is suitable for measuring the pressure or vacuum of corrosive liquid that will not crystallize and solidify.
”” Diaphragm seal pressure gauges are divided into standard type and all stainless steel type, there are difference in material and measuring range between them. Besides of measuring common pressure, stainless steel diaphragm seal pressure gauge can measure the low pressure of 1.6~40Kpa and vacuum. Stainless steel diaphragm seal pressure gauge with flange connector can be used for measuring the pressure of media, in which granule and deposit exist. So the gauges are widely used for measuring the low pressure of corrosive medium in chemical industry.


”õWorking Principium
””The gauge is made up of measuring system (including flange connector and diaphragm seal etc.) pressure transfer system and indicating device (including crank arm, gears, point and dial etc.), and out crust (including crust, cover and glass etc.).
””The working principium of the gauge is that diaphragm can take place elastic distortion under the pressure of medium, and the change is transformed and amplified by gears, then drives the pointer over a dial to provide a pressure reading.

”õTechnical Specifications
””Accuracy: 2.5
””Operating condition temperature: -40~70”ę; Relative humidity ”Ü 90%
””Temperature effect : when working temperature deviates from 20”Ą5”ę, the additional temperature error is not more than 0.4%/10”ę.
