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.
