Float Level Switches – KD12 & KD30 Series

Marine float level switches, whether horizontally or vertically mounted, provide high-level or low-level detection of liquids in all types of vessels.

The KD12 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 micro-switch in the electrical connection housing as the float rise or falls.

 The KD30 switch is mounted vertically in the tank roof and uses a collar float with an internal magnet that activates a magnetic reed contact internal to 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 both horizontal and vertical switch types an optional external test handle allows checking of the switch operation from outside the tank irrespective of actual liquid level.
