Model CR

WHAT IS IT? The Model CR is a rotating paddle style level control that can indicate the presence (or absence) of dry bulk material within a bin or hopper. The unit can be equipped with either 1, 2, or 3 heavy duty microswitches to control a variety of functions or alarms.

WHY IS IT NECESSARY? The Model CR is designed to provide an indication of material level within a hopper or bin without ever opening up the vessel.
