MDS Differential Pressure Gauge

The SIKA differential pressure gauge type MDS with two bourdon tubes are economical instruments for measuring two different pressures and an indication of the differential pressure. They are used in heating systems (supply and return lines) and filter systems.

Differential pressure gauges should be selected with a full-scale value that is at least as large as the maximum pressure occurring in the system. The pressure gauges can be operated at pressures up to the maximum scale pressure, but they cannot withstand overpressure. To ensure good readability of the differential pressure, the differential pressure should not be less than about 20 % of the full-scale value.
