Vertical liquid level switches

The VS 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 into close proximity to 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

The sensor mounts into the top or bottom wall of a liquid storage tank
using either a 1/2” NPT or M16 x 2.0 threaded fitting. The M16 mount
is available in either an internal or external configuration. The output
is a simple N.O. or N.C. SPST, or SPDT reed switch that utilizes
Ruthenium contact points for reliability. Changing from a N.O. output
to a N.C. output is done by removing the float and reattaching it in an
inverted orientation. This change can be done in the field. Electrical
outputs are a single pair or three wires with PVC insulation and
optional lengths of 0.5 m or 2.0 m.
