Horizontal short-swing liquid level sensors

The LDS series of point liquid level switches demonstrates a high
degree of reliability due to the use of non-reactive wetted
components and a unique reed switch designed specifically for level
sensing applications. The sensor utilizes a moving float with an
embedded magnet to activate a reed switch located in the sensor
body. As the liquid level raises the float, it moves a magnet into
close proximity of the reed switch and actuates it to give an open
contact or closed contact switch indication.

The reliability of this sensor results from a very simple operating
principle, a single moving part, media compatible wetted materials,
and a unique reed switch design that has a UL recognized
component certification.

The sensor mounts into the side wall of a liquid storage tank using
an M16 x 2.0 threaded fitting. The M16 mount is available in an
internal or external configuration. The output is a simple N.O. or N.C.
SPST reed switch that utilizes Ruthenium contact points for
reliability. Changing from a N.O. output to a N.C. output is done by
rotating the switch 180° in the mounting hole. This change can be
done in the field. Electrical outputs are a single pair of wires with
PVC insulation and optional lengths of 0.5 m or 2.0 m.
