The product is manufactured using internationally advanced stainless steel pressure sensors and stainless steel film boxes. 

It automatically measures the pressure inside the system to prevent it from being too high or too low. 

It functions as an overpressure alarm and a low-pressure alarm, outputs switch alarm signals, and has an advanced switch locking device to prevent automatic reset. 

The switch can only be reset after manually pressing the reset button. Ensure that equipment, systems, and personnel work within a safe pressure range.

Suitable for different fluid pressure media: refrigerant, fire extinguishing agent, compressed air, industrial gas, air, water, seawater, tap water, river and lake water, well water, etc.
