Diaphragm pressure gauges for differential pressure for chemical applications-high overload protection.

Application.
For differential pressure measurement with low differential pressure and very high static pressure. For corrosive, gaseous and liquid media, also for use in corrosive atmospheres. Since the pressure chambers can be flushed, the units are also suitable for polluted media. When measuring gas or vapour, the instruments must be used in accordance with the safety recommendations of EN 837-2.

Function
Each of the pressures acts on a diaphragm. The diaphragms are connected via a rod. To compensate for the static pressure, the chamber between the diaphragms is filled with pressure transmission liquid. At identical pressures, both diaphragms are in „rest“ position. If the pressures are different, the diaphragms change their shape in the direction of the lower pressure. This displacement is picked up by the movement. The differential pressure is directly indicated by a pointer.
