differential pressure controller switches:, 1)Adjust range: 0.05~0.35MPa, 2)Max. working pressure:1.7Mpa - details see: https://www.machineto.com/differential-pressure-controller-switches-10247808

differential pressure controller switches : a kind of safety switch, Which protects refrigeration compressor from damage of too low oil pressure of lubricating oil. If the oil pressure is too low, the controller will stop the compressor after a while.
FSD35C differential pressure control (oil pressure control) can be used to make the pipes reach a constant flow rate through controlling differential pressure between inlet and outlet pipes in the water system.
FSD35C differential pressure control (oil pressure control) has adjustable differential pressure,and it incorporate a thermal time relay,

Approvals: DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
