Ashcroft & Wika Diaphragm Seals, Chemical Seals & Isolation Rings
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. Diaphragm seals, also known as chemical seals are also used to protect a process fluid from the pressure sensor. BriceBarclay offers a variety of seals for applications where allowing process fluid to accumulate in the pressure port of the sensor would compromise the purity of the fluid or where the metal surface of the pressure sensor might contaminate the fluid.
