YK type pressure controller using butterfly metal film as sensing element,When the medium (liquid or gas)pressure within the pressure system is above or below the rated security pressure ,the dish mental diaphragm within the system jumps instantaneously ,Thus to push the switch contact to be connected or disconnected through a connecting rod .When the pressure drops to the rated recovery value,the dish mental diaphragm is instantaneously reset and the switch is automatically reset.
YK series pressure switch is widely used in hydraulic and pneumatic system pressure control of regrigeration units ,Various types of air conditioning ,air compressor,heat pump,oil pump and air pump,engineering machinery ,mining machiinery,contruction machinery and other industrial equipment with needs of medium pressure regulation and pressure system protection.
1)It can be manufactured according to any pressure value selected by users within the pressure ranger of -100KP~10MPA.
2)Unipolar single-throw or unipolar double-throw,Normally open or normally closed switch contact structure options can be selected by users, While the sealed stainless steel sensor is safe and reliable.
3)By using screw quick coupling or copper tube welded structure, The products are flexibly installed and easily used,with no special installation and fixing mode .
4)Insert and wire-type electrical connectors can be selected by user.
