Brass rub blocks help monitor belt misalignment in bucket elevators and conveyors by detecting heat generated from the friction caused by a misaligned belt rubbing against the brass surface.
A temperature sensor embedded in the brass block measures the heat, and the system triggers an alarm and shutdown once the temperature reaches a trip-point.
Typically, these sensors are installed in pairs on opposite sides of the machine to detect misalignment on both sides. They can be connected directly to a PLC input or, for enhanced safety, integrated with an independent monitoring system such as 4B’s T500 Elite Hotbus™, Watchdog™ Super Elite, or T400N Elite Hotswitch.
Inspection doors are available for easier periodic maintenance and testing of the brass rub block and system.
