MBS3350 / 060G1474 Marine Pressure Transmitter – 0–6 bar (0–87 psi), 4–20 mA, G 1/4A, Pg 11, IP65, with DNV GL/LR/BV/CCS Approvals

MBS3350 / 060G1474 – Marine-Grade Pressure Transmitter with Integrated Pulse-Snubber

The MBS3350 pressure transmitter (model 060G1474) is a high-performance instrumentation solution purpose-built for the maritime industry. Designed to monitor a wide range of onboard systems including hydraulic circuits, lubrication oil, cooling water, fuel oil, and pneumatic controls, this transmitter delivers dependable pressure data essential for safe and efficient vessel operations.

Measurement Performance
The transmitter covers a pressure range of 0 to 6 bar (0–87 psi) and provides a standard 4–20 mA analog output, ensuring seamless integration with shipboard PLCs, alarm monitoring systems, and data acquisition platforms. It offers a typical accuracy of ±0.5% FS (maximum ±1.0% FS), delivering reliable readings for critical system monitoring and diagnostics. The response time is ≤ 4 ms for liquids (viscosity < 100 cSt) and ≤ 35 ms for air/gas, making it versatile for both hydraulic and pneumatic applications.

Superior Build Quality for Harsh Marine Conditions
All wetted parts and the housing are constructed from acid-resistant AISI 316L stainless steel, providing exceptional corrosion resistance against seawater, saline atmospheres, and aggressive fluids commonly found in engine rooms and deck environments. The unit operates across a wide media temperature range of -40°C to 125°C, accommodating both extreme cold and high-temperature engine-room conditions. It withstands a static overpressure of 20 bar and an extraordinary burst pressure of 2000 bar, ensuring operator safety and system integrity even under fault conditions.

Integrated Pulse-Snubber for Dynamic Protection
Unlike many marine transmitters, the MBS3350 features an integrated pulse-snubber that effectively dampens destructive pressure spikes, cavitation, and hydraulic hammer effects. This design significantly extends sensor life in pulsating systems such as pump discharge lines, valve actuation circuits, and cylinder control loops, reducing maintenance costs and unplanned downtime.

Global Maritime Approvals
This transmitter holds type approvals from leading classification societies, including DNV GL, Lloyd’s Register (LR), Bureau Veritas (BV), and China Classification Society (CCS). These certifications simplify newbuild and retrofit approval processes, reducing project lead times and administrative burdens for shipyards and system integrators worldwide.

Connectivity and Environmental Sealing
The pressure connection features a G 1/4A external thread (conforming to DIN 3852-G), a standard interface for hydraulic and pneumatic systems. The Pg 11 angled electrical connector ensures secure, space-saving wiring in confined machinery spaces. With an IP65 protection rating, the housing is fully dust-tight and protected against low-pressure water jets, suitable for engine-room washdowns and exposed deck installations. High vibration resistance and enhanced EMC protection guarantee stable signal output even near large motors, generators, and frequency drives.

Choose the MBS3350 / 060G1474 for your marine and offshore monitoring applications — where marine certifications, pulse protection, and long-term reliability are mission-critical.
