Monitoring of bucket elevators

Kiepe Belt Misalignment Switches SBW are used in bucklet elevator installations for monitoring the true tracking of the elevators belt. The switches will operate if the belt exceeds the permissible deviation from the nominal tracking. The switch´s output signal energizes the connected control units to stop the elevator in order to avoid spillage of material, severe damage and serious downtime.



The monitoring of the true tracking of the buckets is realized by mounting a pair of inductive proximity switches near the headpulley on the carrying side and another pair located near the tailpulley on the return side. Misalignment of the buckets becomes detected as soon as a bucket mistracks into the sensing zone of the proximity switch. The sensing distance of the inductive proximity switches is adjustable by means of a potentiometer accessible from the sensor´s surface. A LED indicates when the sensor´s oscillator field is interfered by a bucket. All switches can be programmed from NO to NC.
