CNG Pressure Gauge is fixed on the intake valve between cylinder and pressure reducing regulator of CNG vehicles to show the pressure of natural gas in cylinder. Through a gas pressure sensor inside, the gauge sends pressure signal to fuel changeover switch, so that the driver get to know the gas volume inside cylinder. Waterproof CNG Pressure Gauge owns patented waterproof craft, avoiding water inflow when you are washing you car, so that the gauge can be used longer.
The main function of cng pressure gauge is directly to measure the gas pressure and transfer it into an electronic signal when the medium pressure effect on the spring pipe system and cause displacement. The pressure coming from the gas can be shown by the indicating hand on the scale, at the same time, trough the sensing magnet and Hall Effect circuit assembled at the free end of the spring the pressure value can be transferred into electronic signal sent to an oil/gas switch. Tube and socket: Phosphor bronze and brass.
