The Musasino FS-M3-1 is a mechanical float switch designed for liquid level detection and control within marine automation and monitoring systems. Mounted in tanks, bilge spaces, or other fluid-containing compartments onboard ships, it provides reliable switching action based on rising or falling liquid levels. As a core component within a vessel’s Marine Control System, it plays a critical role in protecting machinery, triggering alarms, and enabling automated pump control — all functions essential to safe and efficient ship operations.
Key Features
✓ Float-operated mechanical switching mechanism providing direct liquid level detection with contact capacity rated at AC 250V / DC 24V, 15A/2.5A as specified on the nameplate.
✓ Maximum operating pressure of 0.5 MPa, making it suitable for pressurised tank and piping applications subject to confirmation of installation conditions.
✓ SS400 steel construction indicated in the product data, offering structural durability suited to shipboard environments; further material compatibility should be confirmed for specific fluid media.
✓ Designed for integration into shipboard tank level monitoring, bilge alarm, and pump control systems; compatibility with specific panels or controllers is subject to confirmation based on vessel configuration.
✓ Replacement and retrofit considerations should include verification of float dimensions, mounting thread, and electrical termination to ensure a direct fit; nameplate data and original drawings are recommended for confirmation.
Marine Applications
✓ Tank level monitoring in ballast, fuel oil, fresh water, and grey water tank systems across a range of commercial and industrial vessel types.
✓ Bilge level detection systems where automatic pump activation or high-level alarms are required for machinery space safety compliance.
✓ Integrated into engine room automation systems for monitoring service tanks, settling tanks, and drain wells during normal vessel operations.
✓ Used in cargo vessel, tanker, and offshore support vessel applications where reliable level switching is critical to cargo management and operational continuity.
✓ Applicable to newbuild installations and retrofit projects where existing Musasino float switch units require like-for-like replacement within established control system architectures.
Why Marine Engineers Choose
The Musasino FS-M3-1 float switch is valued for its straightforward mechanical operation, clearly specified electrical ratings, and known compatibility with Musasino-based marine control and monitoring systems — reducing uncertainty during replacement planning and maintenance scheduling.
Ideal For
Bulk carriers, tankers, general cargo vessels, offshore support vessels, ferries, and other commercial ship types operating automated tank level management and bilge monitoring systems.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, compatibility verification, onboard commissioning guidance, and integration into existing marine control systems. Retrofit and upgrade support can also be provided depending on the vessel’s installed system configuration. To confirm suitability and ensure correct supply, buyers are encouraged to share nameplate photographs, the full part number, any available wiring diagrams or system drawings, the model and version of the associated control panel or monitoring system, and the vessel name or IMO number where applicable. All compatibility assessments are subject to confirmation based on the information provided.
