Shop SPAN 3.5 inch Center Back Mount Subsea Pressure Gauges
The SPAN 3.5" Face Center Back Mount Liquid Filled Subsea Gauge is a highly durable and accurate pressure gauge designed for harsh environments such as subsea, ROV, military, and marine applications. This gauge features a 3.5" face and a liquid-filled design that minimizes pointer movement, ensuring stable readings and a longer lifespan, even in high-shock and vibration conditions. The center back mount means the gauge is attached and mounted from the rear at the center of the housing, providing a secure installation that is ideal for panel or equipment mounting in tight spaces or specialized setups. The Zytel case and ring provide excellent protection against chemicals, weather, and corrosion, while the patented internal compensating diaphragm (ICD) ensures accurate readings by compensating for temperature and pressure changes, particularly in deep-water applications. Additional features include a white-on-black dial, stainless steel internals, and options for freeze-proof KEM-X Socket Savers, with NIST traceable certifications available. This versatile gauge is perfect for demanding applications that require reliable performance in extreme conditions.
All OneHydraulics SPAN Subsea Gauges come with NIST Calibration Certification.
