Description
The LSR-xxx Series load sensors use current levels to determine
feed rates, tool wear, loss of prime on pumps, mixer viscosity
and all types of overload and underload conditions. They
may also be used to stage pump motors, chillers and other
machinery. These devices combine a current transformer (CT)
with Form C (SPDT) relay contacts to switch alarm circuits,
contactors or any resistive or inductive load. One simple
screwdriver adjustment will calibrate the sensor for all singlephase
or 3-phase applications up to 100hp.
