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 1, 9.
This mechanical deformation is converted into an electrical signal via a Hall magnetic induction circuit, known for its high precision, consistency, and long lifespan.
Typically features three wires: Red (Power +), Black (Ground -), Yellow (Signal Output).
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.
Installed on CNG vehicles between the gas cylinder and the pressure regulator.
Essential for safe operation and efficient fuel management in CNG-powered automobiles and taxis.
This pressure gauge utilizes a high-precision Photoelectric sensor coupled with a Hall magnetic induction circuit for accurate signal conversion.
The gauge is designed for a working pressure of 200 Bar (with a burst pressure rating up to 1000 Bar) and has a durability rating of ≥80,000 operations.
It operates reliably within a temperature range of -30℃ to 100℃ and carries an IP65 waterproof rating for effective protection against environmental elements.
The unit comes with a standard three-wire configuration: Red for Power (+), Black for Ground (-), and Yellow for Signal Output.
It supports 1/4 BSP and M14*1.5 thread specifications with a radial connection orientation.
It is primarily installed on CNG-powered vehicles and taxis between the gas cylinder and the pressure regulator for fuel monitoring and safe operation.
