PDS11 differential pressure switch

Characteristics: Good stability, easy to adjust. High reliability, small time drift. Strong ability of unilateral pressure anti-overload.

Profile:The  PDS11 differential pressure switch is widely used for the water, gas and oil’s pressure control. When the differential pressure is higher than the setting value, the pressure will make the constant spring deformation, which makes the micro switch action and export contact signal, thus realize alarm and control.

Our company specially selects a standard selection for customers, at the same
time, we add to extended special requirements for you to choose, if it still
couldn’t meet your requirements, please list us your photos and tables.
