船用压力开关Marine Pressure Switch

YWK-50-C型压力控制器是可随被控介质压力变化而使电路闭合或断开的电开关。用于船舶、冷冻设备及其它工业设备中与执行机构配套，对气体、蒸汽或液体介质的压力进行两位式控制。

Marine Pressure Switch

YWK-50-C type pressure controller is an electric switch which could close or disconnect the circuit in accordance with the pressure change of the controlled medium. It is applicable to actuating element on ships, refrigerating equipment and other industrial equipment, and the two-position control of gas, steam and liquid pressure.
