Applications for Rotech Motion Sensors/Encoders
Applications for Rotech Equipment, such as Heavy Duty Motion Sensors is as a Speed or Slow Down Switch on plant and machinery.
You can fit them to conveyor belts, elevators, conveyor screws, crushers, mixers, valves, and any other plant equipment that creates a hazard if it stops or runs below its normal operating speed.
Always install them at the end of the drive system.
On a conveyor or elevator, install them on the tail drum, tail roller, snub roller, gravity take-up roller, or any roller that the conveyor belt directly drives. Alternatively, you can fit the ‘Rotech’ wheel-driven motion sensors so they run directly on the return side of the conveyor belt.
If the drive motor, gearbox, drive chains, or drive belts slow down—or if the conveyor belt slips—the conveyor belt and the selected drum or roller will also slow down. The motion sensor then detects this change immediately.
This approach allows you to monitor every critical element of the conveyor system.
Do not fit the heavy-duty shaft sensor to the drive roller or drum unless special circumstances clearly require it.
On conveyor screws, install the heavy-duty shaft sensor on the non-driven end of the screw.
Shaft Sensors can give information on the speed, angular position, direction and number of revolutions completed by a rotating shaft.
Via racks, screws, slides, etc., all of these functions can be translated into linear functions.
Although its use as a Speed Switch is the principle application of “Rotech” Motion Sensors/Encoders, they also fulfil a wide range of other applications in many types of industries.
