Barksdale Bilge Guard Level Switch

Rugged float level switch for reliable bilge level monitoring in marine environments

Able Instruments are Barksdale’s Master Distributor for the UK and Ireland, supplying the Bilge Guard Level Switch for dependable single-point level detection in bilge and sump monitoring applications. Designed specifically for marine and harsh industrial environments, the Bilge Guard provides a simple and robust solution for detecting rising liquid levels and activating alarms or pump control systems.

The Bilge Guard operates using a proven mechanical float switching principle. As the liquid level rises, the float actuates an internal reed contact to provide a clear on/off switching signal. This mechanical design eliminates the need for external power or electronic calibration, ensuring reliable operation in environments where electrical complexity or contamination may present a risk.

Key Features:

• Mechanical float level detection: Proven float and reed contact design provides reliable single-point level switching without external power.
• Designed for bilge monitoring: Optimised for bilge water, wastewater, and sump level detection in marine and harsh industrial environments.
• Rugged construction: Stainless steel stem and mounting bracket with a polyethylene float for durability in demanding conditions.
• Optional test function: Selected variants include an integrated test lever for routine functional checks without raising the liquid level.
• High ingress protection: IP67 / IP68 rated for reliable operation in wet, flooded, or submerged conditions.
• Simple and dependable operation: Mechanical switching principle eliminates the need for calibration or electronic setup.
• Flexible mounting tolerance: Designed for vertical installation with tolerance for slight angular deviation.
• Marine approvals available: Suitable for shipbuilding and marine applications where certification is required.
