Marine Pressure Gauge (DNV / BV / CCS Certified)

-- Steady & Reliable Manufacturer --

Product Overview

Our Marine Pressure Gauges are purpose-built to survive the harsh demands of ocean-going vessels, offshore platforms, and port facilities. Every unit in this series is manufactured, tested, and certified to the requirements of leading international classification societies, including DNV GL (Det Norske Veritas), Bureau Veritas (BV), and China Classification Society (CCS). Constructed with a full stainless steel case and wetted parts resistant to salt spray and high humidity, these gauges provide reliable pressure indication on engine rooms, deck machinery, fuel systems, ballast systems, and hydraulic steering gear — where certification is a statutory requirement and failure is not an option.

Key Features

Type-approved by major international marine classification societies (DNV, BV, CCS), meeting strict marine environment standards for vibration, shock, salt-mist, and humidity resistance.
Full stainless steel case and wetted parts provide maximum resistance to salt-air corrosion and condensation common in marine engine rooms and topside installations.
Liquid-filled (glycerin or silicone oil) option absorbs engine room vibration and propulsion pulsations, ensuring steady, readable pointer indication under way.

Typical Use Cases

Marine Engine Rooms: Main engine lube oil, fuel oil, and cooling water system pressure monitoring where classification certification is required.
Ballast & Bilge Systems: Pressure indication on pumps, piping, and valves handling seawater ballast and bilge fluids.
Hydraulic Steering Gear: High-pressure hydraulic system monitoring on steering gear and stabilizer units.
Cargo Pump Systems: Pressure control on tanker and bulk carrier cargo transfer pump skids.
Offshore Platforms: Topside and subsea control panel pressure monitoring requiring classification approval for insurance and regulatory compliance.

Competitive Benefits

Multi-Society Certification: A single product family certified by DNV, BV, and CCS simultaneously simplifies procurement for shipbuilders and owners operating under different flag-state requirements.
Regulatory Compliance Assurance: Class-approved certificates are included with every shipment, eliminating delays during pre-delivery surveys and port-state control inspections.
Salt-Air Durability: 316L stainless steel construction and IP65 protection deliver a service life far exceeding brass or aluminum alternatives in high-humidity, salt-laden marine atmospheres.
Vibration Resistance: Glycerin or silicone oil filling provides continuous mechanical damping, critical on high-vibration vessels including offshore supply vessels and high-speed ferries.
Global Spares Support: Standardized designs stocked at our warehouse ensure rapid replacement supply to any port worldwide with minimal lead time.

Payment and Shipping Details

We accept T/T (30% deposit, balance against B/L copy) and irrevocable L/C at sight for marine-certified equipment. Shipping is coordinated via FOB Shanghai/Ningbo or CIF destination port; for vessel retrofit projects, we can also arrange direct delivery to ship chandlers or dry-dock facilities worldwide. Classification-certified models are stocked for dispatch within 7–10 working days for common ranges; special pressure ranges or connection types require 15–20 working days. All certified gauges are shipped with original type-approval certificate copies and individual test reports.
