hongsen pressure switch high and low pressure controller p830hm p830 manual automatic pressure control can be equipped with nazi

The P series pressure controllers are used to protect the compressors of refrigeration or air conditioning devices, preventing them from experiencing low suction pressure or high discharge pressure.
The P series pressure controllers can also be used to start and stop the compressor and the fan of the air condenser.
The P series pressure controllers can also be used in equipment such as pumps, fire fighting, boilers, hydraulic, ironing, vacuum, etc.
The P series pressure controllers are equipped with a single-pole double-throw (SPDT) switch, and the operating value is determined based on its set value and the pressure at the interface.
The P series pressure controllers are equipped with copper airbox connections for use in Freon refrigerant systems. They can also be equipped with stainless steel airbox connections to meet the needs of corrosive gases or liquid systems, such as liquid ammonia.
The P series pressure controller's clever micro-switch structure ensures a reliable and quick switching function.
