Description
Working Principle
YK type pressure controller using butterfly metal film as sensing element,is accused of medium pressure rises to a certain value,the butterfly metal diaphragm produceinstability,enthusiastically through a push rod ,to switch contact on (or )off,was charged with medium pressure decreases to another setting,butterfly mental film will suddenly back to its original state,make the switch contactor to disconnect(or allow),so as to realize control of the pressure,the products have the advantages of small size ,low cost,safe and reliable ,easy to use,long service life,ETC
Application
YK series pressure controller is a kind of advanced miniature pressure switch ,is widely used in the air-conditioning,refrigeration units,all kinds of pumps ,engineering machinery,mining machinery,construction machinery and other large machinery and equipment of liquid level ,pressure control of hydraulic ,pneumatic system ,and other needs to adjust the medium pressure ,protect the pressure in the system of industrial equipment.
