Products Instruction
The pressure controller has 2 categories in term of YK20PS(M)(Automatic and Manual) of four series,YK20PSA series, YK20PSB series,YK20PSC series and YK20PSD series. The YK20PS is called automatic reset pressure switch with range of high and low pressure and YK20PSM is called manual reset pressure switch.
There are many different type/size of pressure switches which can be determined by customers in use of different machines. The series are external / internal whorl ,Brass Tube and pressure switch with cables and inserts.
(Remark: YK20PSA and YK20PSB also apply to manual type)
Application
The pressure controller functions to control pressure transmission power switch on/off based on the principle of instability jumping when the dish metal diaphragm is under uniform pressure load.
It is mainly used for protection and control of high and low pressure on household, commercial and automotive air conditioner refrigerating systems, and can also be used to protect and control high and low pressure on air compressor, hydraulic machines, water pump and heat pump,etc.
Operation/working principles
when the medium (liquid or gas) pressure within the pressure system is above or below the rated security pressure, the dish metal 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 metal diaphragm is instantaneously reset and the switch is automatically reset.
