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
