KD & LSA Series Mechanical Marine Float Level Switches

KD & LSA Series Mechanical Marine Float Level Switches

Our marine float level switches, whether horizontally or vertically mounted, provide high-level or low-level detection of liquids in all vessels. A wide range of liquid level switch models is available, including Mobrey 92mm square flange replacements, to suit each specific application.

 

Horizontal or Vertical Mounting

The KD12 float level switch is mounted horizontally in the tank wall, and uses a cylindrical float with a magnet attached to the end of the lever arm that activates a reed type magnetic microswitch in the electrical connection housing as the float rise or falls.

The KD30 float level switch is mounted vertically in the tank roof and uses a collar float with an internal magnet that activates a reed type microswitch in the stem of the switch as the float rises or falls. Collars located on the stem limit the travel of the float (or floats on a multipoint switch) and ensure that the float holds the reed switch in the energised position while the alarm condition is present.

For either KD series switch type an optional external test handle allows checking of the switch operation from outside the tank irrespective of actual liquid level.

The LSA Series of high level alarm switches include both side and top (cranked arm) mount switches. Corrosion resistant Gun Metal housings have an IP68 rating and the switch can be specified as ATEX EExd certified
