Mounting according to affixed symbols
⊕ high pressure, ⊖ low pressure
Pressures p1 and p2 act on the ⊕ and ⊖ side of the measuring chamber, separated by the pressure-loaded magnetic piston or magnetic piston。
The difference in pressure causes an axial movement (deflection) of the piston supported by the measuring range spring.
An annular magnet mounted on the instrument pointer follows the magnet integrated in the piston so that each piston position is assigned a defined position of the pointer.
This design enables the complete mechanical separation of the measuring system and the indication while eliminating any leakage to the outside.
With the volume flow from the ⊕ to the ⊖ side in the measuring chamber is minimised by the mechanical design and will not interfere with standard processes.
