Description

Diaphragm seals are used to protect pressure measuring instruments in demanding applications under difficult conditions. These diaphragm seal systems, consisting of a process transmitter, pressure sensor, pressure gauge or pressure switch with diaphragm seal, can be combined individually for each customer application. For this, a wide range of different designs, process connections, mounting types and wetted materials are available.

Diaphragm seal models with flange connections are available with flush or internal diaphragms, in tubular design or as in-line diaphragm seals. The variants mentioned are also available in a cell-type design.

Special features

Flange with flush welded diaphragm
Common standards and nominal widths available
Wide variety of different materials and material combinations
