A unique
patented Magnetic Linkage
in the S-D™ Liquid Level Switch isolates the electrical
compartment, containing one or two switches, from controlled
product. This reduces maintenance and improves sensitivity.
The sealed switch compartment and sealed leads yield highly
reliable operation. A variety of switch types, options,
mounting choices and thumbwheel adjustable ranges is available
to fit your specific application. The S-D™ Level Switch
is very sensitive and economical. The force required to
depress the diaphragm and trip the switch(es) is in inches
water column. The simple design has been proven rugged and
reliable providing long life in the most severe applications.
