Diaphragm seal systems
with short delivery times

Fast and reliable
These combinations of diaphragm seals with pressure measuring instruments
particularly stand out for their very fast availability.

The diaphragm seal systems can be used for processes withgases, compressed air or vapour, with liquid, pasty, powdery
and crystallising media and also with aggressive, adhesive,
corrosive, highly viscous, environmentally hazardous or toxic
media.

The diaphragm made of stainless steel provides for the
separation from the medium. The pressure is transmitted tothe measuring instrument via the system fill fluid which is
inside the diaphragm seal system.

Diaphragm seals – combinations
and accessories
WIKA diaphragm seals can be connected to almost allpressure gauges, process transmitters, pressure switches
or pressure sensors. Mounting may be made via a directconnection, a cooling element or a corresponding capillary.
The combined systems can therefore withstand a pressureof 10 mbar up to 3,600 bar at extreme temperatures(-130 … +400 °C) and with a wide variety of media, thus

Technical information

Operating principle of diaphragm
seal systems
By using diaphragm seals, pressure measuring instruments
can be adapted to even the most difficult of conditions withinprocess industries. A diaphragm separates the medium tobe measured from the pressure measuring instrument. Theinternal space between the diaphragm and the pressure
measuring instrument is completely filled with a fluid.
The process pressure is transmitted by the elastic diaphragm
into the fluid and from there to the measuring instrument.
A wide variety of designs and material combinations areavailable for customer-specific solutions.
The accurate pressure measurement of all ranges
from approx. 10 mbar up to 3,600 bar, even at extreme
temperatures (range -130 … +400 °C), is thus possible under
extreme conditions.
