Model 16 — Belt Alignment Control


The Model 16 is a heavy-duty conveyor belt mis-alignment switch that either provides an indication or a shutoff of the conveyor during a drift condition in order to prevent further damage to the conveyor belt. The output contacts of the Model BA can control up to two separate circuits – one for conveyor shutdown and one for an alarm.


The model 16 is relatively inexpensive protection that provides benefit by saving the time, money, and labor associated with replacing a damaged conveyor belt.
