BLS 9200 Bilge Level Switch - Never Compromise On Safety

Bilge level switches and bilge alarms are safety critical components for detecting liquid in voids. They need to withstand years of installation in difficult environmental conditions,yet operate immediately and reliably to indicate leakage or flooding.

Fully Submersible Marine Approved Bilge Water Alarm / Bilge Level Switch

When considering bilge level sensors, it would be easy for a ship builder or owner to try and make economies by using cheaper devices, often constructed with poor quality materials and design.  PSM believe that this approach both comprises safety, and is a false economy as maintenance and replacement costs will always exceed those of installing “the right device first time”.

The integral manual checking device in the BLS 9200 fully submersible marine approved bilge alarm/water level switch conforms to class rules without complicating installation. Siting and mounting are also simple, requiring only a two bolt fixing. The self-draining, fully shrouded design prevents interference of operation from obstructions or floating debris.

Due to the harsh environments that this bilge water level switch is likely to encounter, extensive successful testing has been undertaken, exceeding the required environmental testing required for Marine Type Approval laid out in IACS Unified requirement E10 and the relevant sections of IEC945.
