HORIZONTAL

LIQUID LEVEL SENSORS

LS Series

High- or low-level switching

N.O./N.C. SPST or SPDT outputs

Mounted on the side wall of a tank

Certified reed switch (UL component listed)

Choice of several non-reactive wetted materials

Many different configurations available

The LS 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.

Features

 Voltage rating up to 250VAC

 Current rating up to 1.0 amp

 Compact design and low profile

 Optional cable lengths

 Includes mounting hardware

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.

Applications

 Water and fuel storage tanks

 Full and/or empty detection

 Pump on/off controls

The sensor mounts into the side 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 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.

 Marine bilge and ballast tanks

 Flood detection and prevention

 Coolant level indication

 Livestock watering tanks

 Irrigation systems

 Water treatment plants

 Waste water tanks

 Chemical storage and processing
