CNG Manometer

Application:CNG pressure gauge is mainly used in measure the pressure of the natural gas inside vehicles’ gas tank and high pressure lines.In addition it also transfer the measured value of the gas pressure into an electrical signal and send it to the oil/gas switch in the driving control board in order to accurately indicate the pressure. Operation mechanismThe main function of the sensor are directly to measure the gas pressure and transfer it into an electronic signal.when the madium 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.
