A CNG gas pressure gauge is a crucial component for natural gas vehicles, manufactured by top suppliers in China. This gauge is installed on the inlet valve connecting the CNG pressure regulator to the gas cylinder and is designed to accurately display the pressure of natural gas within the cylinder. Utilizing an advanced internal gas pressure sensor, it transmits real-time pressure signals to the fuel/gas conversion switch located in the driver’s cab, enabling users to effortlessly monitor the gas volume in the cylinder, Additionally, a matching indicator light-type conversion switch is provided. When the onboard gas tank is fully charged (pressure between 180-200 bar), all four green indicator lights illuminate, while the red light remains off. As the pressure decreases, the indicator lights provide critical alerts: the fourth green light turns off at 165-155 bar; the third green light goes off at 130-120 bar; the second green light extinguishes when the pressure falls to 90-70 bar; and finally, the fourth green light turns off between 45-35 bar, triggering a red alarm light. At this stage, the remaining gas is sufficient for the vehicle to travel approximately 15-25 kilometers, depending on the vehicle model. Our factory also offers a digital conversion switch option for enhanced monitoring. This product is ideal for those seeking high-quality CNG solutions from trusted suppliers in China
