Misalignment Monitors for Bucket Elevators
Misaligned belts and pulleys cannot only damage an elevator; they are also one of the main risk factors for dust explosions in bucket elevators.
4B offers a range of contacting / mechanical and non-contacting sensors to detect misalignment on bucket elevators as well as compatible hazard monitoring systems.
