Differential pressure measuring instruments with compression springs are primarily designed and built for the industrial and sanitary measuring technology sectors. 
These instruments fully consider the needs of the gas, water and air supply sectors and are also used for the treatment of such media.

These measuring instruments are suitable for liquid and gaseous media in so far as these are not aggressive or highly viscous and do not crystallise. Moreover, they must
not contain any magnetic material.

Differential pressure measuring instruments with electric microswitches are suitable for controlling and regulating process sequences by means of the given process pressure.


The robust, compact measuring system for measuring the differential pressure comprises a diaphragm, which is loaded on both sides by the springs which determine the
measuring ranges. 

If the diaphram is loaded with a varying pressure – the differential pressure - a deflection occurs which is transferred by a piston to the pointer mechanism or microswitch, respectively, to cause a pointer deflection proportional to the differential pressure and actuate the microswitch.
