This Marine Fuel Pressure Gauge (Marine Fuel Pressure Gauge) is designed for harsh marine environments and is positioned as a high-end industrial-grade monitoring instrument. Its basic construction uses a high-strength stainless steel housing with corrosion-resistant bellows or diaphragm components, designed to ensure precise pressure measurement of the fuel system. The core technology advantage lies in its excellent shock resistance and long-term stability. It can still maintain a measurement accuracy of ± 1.6% or even higher under the severe vibration caused by high-speed engine operation and wave impact. For the special needs of navigation, the product integrates anti-salt spray erosion and IP65/IP67 protection design to ensure that the performance does not decay in humid and salty environments. In terms of technical specifications, the product usually covers 0 to 15 PSI or a wider range, supports a variety of interface specifications such as 1/4 NPT, and meets the installation requirements of small yachts to large ocean-going freighters. The design emphasizes economic benefits. Through accurate monitoring of pressure fluctuations, the crew can help identify filter blockage or pump failure in time, thereby reducing fuel consumption and extending the maintenance cycle of the engine by more than 30%. Its structure and configuration are diverse, providing different versions such as mechanical pointer type and LED backlight digital type, and are widely used in ship main engines, generator sets and fuel distribution systems, showing strong environmental adaptability and multi-medium compatibility, and is an essential tool to ensure navigation safety.

Double-layer stainless steel anti-corrosion shell
316L grade stainless steel, with anti-salt spray coating, in the long-term seawater exposure environment can not only resist corrosion, but also extend the service life of the instrument by more than 5 years compared with ordinary materials.

Oil-filled high-efficiency shock-resistant technology
filled with high-purity glycerin or silicone oil, it can absorb more than 95% of mechanical vibration, prevent the pointer from shaking, and provide clear and accurate readings even in extreme wind and waves.

Precision bellows sensing element
the sensing accuracy error is controlled within ± 1.0%F.S, which can sensitively capture the slight pressure change of 0.1Bar and effectively prevent the engine flameout risk caused by fuel pump cavitation.

Wide temperature range environment adaptability
with extreme temperature difference of -40°C to 70°C, the instrument can work accurately without recalibration when the ship sails from the polar cold sea area to the tropical sea area.

Infrared LED backlit night vision system
equipped with high-contrast dial and anti-glare LED light source, the light is uniform and not dazzling, ensuring that the crew can instantly capture abnormal pressure data in the cabin during night navigation or low light.

Modular quick installation interface
Standard threaded interface and reinforced sealing gasket are standard, reducing installation time by 40%, and can withstand 1.5 times the instantaneous overload pressure pulse to prevent system leakage.
