BLS 9200 Bilge Level Switch

BLS 9200 Bilge Level Switch by PSM Marine from Procon Instrument TechnologyThe BLS 9200 Bilge Level Switch has been designed by PSM Marine to be compact, but a rugged bilge water level alarm switch specifically for marine bilge level measurement on vessels of all sizes.

It is a fully Submersible Marine Approved Bilge Alarm/Water Level Switch

The integral manual checking device in the BLS 9200 fully submersible marine approved bilge alarm/water level switch conforms to class rules without complicating the installation. A two bolt fixing means the siting and mounting are also simple. 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.




BLS9200 Bilge Level Switch features

  • Rugged and compact all-stainless steel design with EPR cable resistant to seawater, fuel oil and hydraulic fluid ensures reliable operation over years of service
  • Compact in size with a mechanical mounting using a two-bolt mounting bracket means that installation and commissioning is simple and fast
  • Self-draining cage design prevents fouling of the float from obstructions or floating debris in the bilge, as well as protection from false-switching
  • Integral switch test lever allows full testing of the float movement and switch functionality ensures routine safety tests can be carried out for peace-of-mind
