The design of GEMS bilge water level switches combines reliable switching in contaminated liquids with compact dimensions.These switches
have been developed for general naval and industrial applications. They have protective housings which dampen the movements and turbulence
of the medium and maintain their reliable operation even if there is solid matter in the bilge water.
Acceptance and Approvals
Various civil, military and naval approvals are on hand for many of these products. Please ask for further details.
Applications
LS-240-3E: This switch has extremely robust construction. It is perfectly suitable for applications on ships and wherever heavy mechanical loads occur.
The LS-240-3E has been accepted by the Germanischer Lloyd, among others, and approved for application by the German Navy.
LS-270-E: This bilge water level switch has been developed especially for low level alarms and can monitor levels as low as 35 mm. As the cable is vulcanized the
switch is submersible to “IP67”. The float can also be constructed as an interface level indicator.
The LS-270-E has been accepted by the Germanischer Lloyd, among others, and approved for application by the German Navy.
LS-750: With a compact-sized float, slosh shield and weighted collar, the LS-750 provides liquid level detection for a wide variety of applications. Suspend in stand
pipes or sumps for leak detection duty, or drop into wells for ground-water monitoring. Supplied with 7.5m of waterproof cable.
