Product Description Differential Pressure Controls switches FSD series differential pressure control is 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.
FSD series differential 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.
FSD-C and FSD-T series all have adjustable differential pressure,but FSD-T series incorporate a thermal time relay.
Approvals: DnV,Det norske Veritas(Norway),CQC(China),CE (Europe). Type and data
