Bilge Alarm Sensors typically feature a size range of 50-150mm in diameter, with marine-grade stainless steel (316L) or corrosion-resistant plastic housing. Operating viscosity range is 1-1000 cP, with buoyancy thresholds adjustable between 5-50mm liquid depth. Common materials include PTFE, PVC, or polypropylene for float switches.
Marine Monitoring Systems often comply with IMO SOLAS standards, with IP68 waterproof ratings. Sensor accuracy is ±1% FS, operating in temperatures from -20°C to +70°C. System voltage ranges from 12-24V DC, with output signals of 4-20mA or RS485. Enclosure materials are typically aluminum or fiberglass-reinforced polyester.
Float switches in bilge alarms have a specific gravity range of 0.6-1.5, with cable lengths of 2-10m (marine-grade tinned copper). Pressure sensors in monitoring systems handle 0-10 bar, with response times under 100ms. Viscosity compensation is automated for fluids up to 5000 cP.
