Differential pressure gauges with magnetic pistons are suitable for all applications with high static pressures.

They are produced in compliance with EN 837-3 standard. Differential pressure gauges can be used for measurements of all liquids, gases and vapour that do not have corrosive effect on copper alloys and its viscosity allows for use of measuring mechanism made of stainless steel class 1.4305. For mediums of higher viscosity it is possible to use pressure gauges with separating membranes.

Differential pressure gauges with magnetic pistons may be used in applications for measurements of small pressure differences even in high static pressures. This design finds its application in wide range of operations, pressure gauges may be supplied with piston and spring or with a membrane, in wide range of materials - brass, alluminium, stainless steel. Maximum environment temerature -20 up to 60°C, medium temperature Tmax 100°C. Dother design options on individual request - with switching contacts, analog output, special scale design, connection threads, etc.
