| DIAPHRAGM PRESSURE GAUGES | | |
| | | | |
| Brief introduction: | | | |
| Diaphragm pressure gauge is composed of a conventional pressure measuring |
| instuments,a connector and a diaphram seal .this combination enables a general |
| purpose pressure gauge to measure media of stong corrosion,high temperature, |
| high viscosity,containing suspended matter or crystallizing. | |
| | | | |
| Applications: | | | |
| diaphragm gauges are university used in petrochemical,alkali,chemical fiber, |
| pharmaceutical,metallurgical,and food industies | |
| | | | |
| | | | |
| Corrosion-proof properties | | |
| Choose various pressure gauges combined with appropriate separator according to |
| enviromental conditions.Choose material of diaphragm and housing compatible with |
| corrosive media. | | | |
| Diraphragm meterial:0Cr17N112M02(316);MONEL(Cu30Ni70);Hastelloy(H276c); |
| TANALUM(Ta);Fluoroplastic(F4) | | |
| Flange material:0Cr17N112M02;316+F4 | | |
| Seals material:Nitrile Rubber;Viton,Silicone rubber;Fluoroplasitc | |

| Configuration principle: | | |
| | | | |
| This illustraiton shows the operating principle of the diaphragm pressure gauge. |
| the diaphragm is deflected by the pressure of medium P,and an equivalent |
| pressure P" is generated.with transmitting through working fluid,the pressure P' |
| deflect the elastic element of a pressure measuring instrument which thereafter |
| shows the pressure value | | |
| | | | |
| | | | |
| Level Difference of diaphragm pressure gauge seals liquid | |
| | | | |
| When a diaphragm pressure gauge is mounted with pressure gauge and diaphragm |
| seal at different positions,the effect of level difference should be taken into |
| consideration(especially for a diaphragm gauge with capillary).As the illustration |
| shows,with a S.G.of the working fluid at approx.1 and a level differnce of 1m, |
| the pressure difference is approx 0.01mpa/cm2 | | |
