Littelfuse LSR-230 Load SensorProduct Description

Model LSR-24, LSR-115, & LSR-230 Load Sensors use current levels to determine feed rates, tool wear, loss of prime on pumps, mixer viscosity, and all types of over and under load 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 single phase or three phase applications up to 100 Hp. The LSR-24 uses 24 VAC control voltage; the LSR-115 uses 115 VAC control voltage; and the LSR-230 uses 230 VAC control voltage.
