Description
This tongue diaphragm seals with union nut are used to protect pressure
gauges from high temperatures, aggressive or corrosive fluids.
They avoid that the medium flows into the instrument, where deposits
could be built and generate wrong measurements or pollution of the
process.
Tongue seals have a large membrane surface in relation to the small
connection size. That’s why they can be used for measurement of lower
pressure ranges compared to threaded seals with flush diaphragm.
Tongue seals should not be used in pipes with strong flow of the medium.
Chemical seal can be mounted to mechanical pressure gauges,
switches or transmitters directly or with a cooling element. The filling
fluid of the measuring system has to be choosen compatible to the
application.
