Diaphragm flange seal – WINNERS

Product Description

Diaphragm seals consist of an elastic element that insulates the process fluid from the sensing element,transmitting pressure by compression of the liquid in the separation chamber.

In the presence of specific physical and chemical properties that are not compatible with the sensing element,the metal diaphragm material needs to be adjusted.Our choice of metal diaphragms are SS316L,Titanium,HC276 and Tantalum.

Detailed description

A diaphragm seal is a flexible membrane that seals and isolates an enclosure.The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Common uses for diaphragm seals are to protect pressure sensors from the fluid whose pressure is being measured.

Diaphragm seals (also known as chemical seals or gauge guards) are also used to protect a process fluid from the pressure sensor. Examples of this use are:

● Sanitary processes (food, pharmaceuticals, etc.) where allowing process fluid to accumulate in the pressure port of the sensor would compromise the purity of the fluid (such as milk getting into the pressure port of a pressure gauge and spoiling).

● Very pure process fluids, where the metal surface of the pressure sensor might contaminate the fluid (such as copper ions from brass leaching into ultra pure water).

● Pneumatic systems where small changes in pressures must be eliminated, such as those controlling air bearings.
