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'.

High-temperature version, model 990.45

Model 990.45 is a high-temperature version consisting of the upper and lower body of a diaphragm seal. The lower body of the diaphragm seal can optionally be designed with flushing connections.

These components have been developed explicitly for applications with very hot media. The process connection is available in the established dimensions in line with the usual standards for this market.

Mounting of the diaphragm seal to a measuring instrument is usually made via a flexible capillary.
