Broken finger float level switch KD SERIES

for shipsfor storage tanks

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 microswitch 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 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 external test handle allows checking of the switch operation from outside the tank irrespective of actual liquid level.
