Diaphragm monitoring system, model DMS27
The WIKA combination of diaphragm seal, pressure measuring instrument and monitoring element is ideally suited for
the harshest measuring tasks. The system can withstand
aggressive or hot media.
The patented diaphragm monitoring has been designed
specifically for the highest safety requirements in the chemical and petrochemical industries.
On the double-diaphragm system a second, internal
diaphragm in the pressure measuring instrument ensures the
reliable separation of the environment and the process in the
event of a diaphragm rupture. The measuring function of the
overall system remains unrestricted, nevertheless it must be
replaced immediately.
Mounting of the diaphragm seal to the pressure measuring instrument is made as direct mounting as standard. A
fluid inside the system, which is explicitly chosen to suit the
particular application, hydraulically transmits the pressure to
the pressure measuring instrument.
Diaphragm monitoring systems with the WIKA model 990.27
diaphragm seals are used successfully in applications with
hydrofluoric acid content.
The model DMS27 is a patented WIKA development,
see e.g. patent DE 19949831, and is subject to further
pending patents, e.g. US 2018180505, DE 102016015447,
CN 108240885.
