The LLF70 series is designed for fitting
through a tank wall from the outside,
where access to the inside for fitting is not
possible.
These devices are particularly suitable for
detecting low levels of liquids in the
bottom of tanks and containers, and for
lower SG liquids. Typical applications
include vending machines, commercial
dishwashers and auxiliary tanks on
vehicles.
These are manufactured in a variety of
plastics, with a choice of gasket materials,
to suit most commonly used liquids.
The switch action may be reversed by
mounting the device with the float able to
move upwards away from the body, instead
of the more normal downwards direction.
Available with either flying leads or M12
socket for electrical connection. Cable
sets with M12 plugs are also available.
Custom versions can be made for
particular applications. Please contact
Cynergy3 with your requirements.
