Level monitoring in bag filters

Level monitoring in dust filter hoppers is indispensable in order to ensure fault-free operation of the filter. If the hopper is over-filled, the filter bags may be damaged, and may have to be removed. The replacement of the filter bags can delay the process or even interrupt production. These interruptions cost time and money. Ultrasonic sensors such as the UM30 or vibration level switches such as the LBV300 effortlessly fulfill the level monitoring requirements.
