Description

Diaphragm seals are used for the protection of pressure measuring instruments in applications with difficult media. In diaphragm seal systems, the diaphragm of the diaphragm seal effects the separation of the instrument and the medium. The pressure is transmitted to the measuring instrument via the system fill fluid which is inside the diaphragm seal system.

For the implementation of demanding customer applications, there is a wide variety of designs, materials and system fill fluids available.

For further technical information on diaphragm seals and diaphragm seal systems see IN 00.06 'Application, operating principle, designs'.

The model 981.50 is ideally suited to fulfil the high requirements of sanitary applications. It can be optimally integrated into pipelines via the BioConnect ® fittings, fulfils all hygienic design requirements and is EHEDG-certified.

In-line diaphragm seal, model 981.50

The diaphragm seal systems can withstand the cleaning vapour temperatures occurring in the SIP processes and thus ensure a sterile connection between the medium to be measured and the diaphragm seal.

Mounting of the diaphragm seal to the measuring instruments may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary.

The availability of the diaphragm seals for common pipe standards and nominal widths simplifies integration into already existing pipe cross-sections.

Special features

Dead-space free installation in pipes
Self-draining in all mounting positions
Quick cleaning, without residue
Suitable for SIP and CIP
EHEDG-certified and 3-A-compliant
