Model FS
WHAT IS IT? The Model FS is designed to provide indication of presence or absence of dry bulk material on a conveyor belt. Each unit is equipped with one or two output micro-switches which can provide a positive shut off. The output contacts of the Model FS can control up to two separate circuits, one for machinery shutdown and one for an alarm.
WHY IS IT NECESSARY? The Model FS is versatile enough to be used in a variety of applications; it can provide proof that material is actually flowing from a chute onto a conveyor belt, or it can be used to actuate a misting system to reduce dust only when material is present.
