Diaphragm Seals

---

All Cella diaphragm seals feature:
 

• top part removable from process connection without loss of filling fluid.

• welded part of diaphragm never exposed to process fluid.

   

Models are available for off-line or on-line installation, with threaded or flanged process connection, recessed or extended diaphragm, direct or remote coupling to instrument.
 

In addition to st. st. standard, wetted parts can be supplied in special materials such as PTFE lining, Monel, Hastelloy C, Tantalum, etc.
 

Various filling fluids cover temperatures ranges from -40 to +300°C depending on application.
 

Diaphragm seals are selected and coupled to instruments so that the maximum error due to temperature effect never exceeds 1%.
