HORIZONTAL SHORT-SWING
LIQUID LEVEL SENSORS
LDS Series
High- or low-level switching
N.O./N.C. SPST output
Mounted on the side wall of a tank
Certified reed switch (UL component listed)
Body and float made from glass filled nylon 6.6
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.
Features
Voltage rating up to 250VAC
Current rating up to 1.0 amp
Compact design and low profile
Optional cable lengths
Includes mounting hardware
Full and/or empty detection
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
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.
