Milltronics MSP-7 motion sensor
■ Overview
■ Application
The MSP-7 motion sensing probe can detect changes in the
rotation and movement of ferrous equipment. When connected
to a PLC it can warn of malfunction and signals to stop or slow
down equipment, preventing costly failure or downtime.
Its reliability makes it a very cost effective sensor.
The single setpoint system suits most industrial applications.
This versatile unit can be used on tail pulley shafts, driven
pulleys, motor shaft sensing, belt or drag conveyors,
screw conveyor flights, bucket elevators, fans and pumps.
An NPN open collector 3-wire output allows for versatile connection to most PLC models and a large dynamic range ensures that
the MSP-7 can detect changes in target speed for a variety of
applications.
• Key Applications: tail pulleys, motor shaft sensing,
screw conveyor flights, bucket elevators
Milltronics MSP-7 is a heavy-duty 3-wire motion sensor that
provides an NPN open collector output to PLCs.
■ Benefits
• Up to 100 mm (4 inch) gap between target and probe
• Corrosion resistant construction
• General purpose, suitable for majority of industrial applications; rugged probe designs provide unmatched reliability
