Application
For differential pressure measurements at very high static pressures. For gaseous and liquid, non-adhesive media that are not highly viscous. Particularly suitable for monitoring filters, pumps, pipe systems and cooling circuits.
Description
The pressures act on two pressure chambers separated by a magnetic piston. If there are different
pressures in the chambers, the magnetic piston is axially displaced against a compression spring.
The magnetic piston transmits this displacement to the pointer by means of a ring magnet mounted to
the pointer hub. The differential pressure is directly indicated. The complete mechanical separation of
pressure chamber and display excludes the possibility of leaks.
