Характеристики

BLPS-YK micro refrigeration automatic pressure switch

Application

It is mainly used for high or low pressure protection and controls on household, commercial and automotive air conditioning refrigerating systems, and can also be used to protect and control high or low pressure on air compressor, hydraulic machines, various equipment and tools.

 

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.
