,

Introducing our premium CNG Pressure Gauge (Sensor), an essential component for Compressed Natural Gas (CNG) vehicle systems. Manufactured in China, this top-quality gauge is designed to effectively monitor the pressure within onboard gas storage cylinders and high-pressure pipelines.

,

Our CNG Pressure Gauge not only delivers a clear visual indication of gas pressure but also converts this pressure into an electrical signal. This crucial data is transmitted to the fuel switch control panel located in the driver's cabin, allowing for precise monitoring of the remaining natural gas volume. As a reliable supplier and factory of automotive components, we ensure that our products meet the highest standards for performance and durability.

Product Features
Pressure Sensing
The gauge uses a sensitive element (such as a Bourdon tube made of Phosphor Bronze Qsn6.5-0.1 or Stainless Steel SUS316L) that deforms elastically under pressure.
Signal Conversion
This mechanical deformation is converted into an electrical signal via a Hall magnetic induction circuit, known for its high precision, consistency, and long lifespan.
Wiring
Typically features three wires: Red (Power +), Black (Ground -), Yellow (Signal Output).
Display & Monitoring
The primary display shows pressure directly on the dial. The electrical output signal connects to a compatible dashboard switch (e.g., indicator light or digital display type), providing the driver with real-time information on gas reserves.
Application
Installed on CNG vehicles between the gas cylinder and the pressure regulator.
Function
Essential for safe operation and efficient fuel management in CNG-powered automobiles and taxis.
