Rub Block Kit - for belt alignment detection - 1

Product DATASHEET Datasheet PRODUCT Rub block, Inspection Door, Gasket, Shim, Bolts and Washers. Brass rub blocks monitor for belt misalignment problems on bucket elevators and conveyors by detecting heat generated by the friction of the misaligning belt rubbing against the brass. A temperature sensor within the brass block provides the temperature reading and the system generates an alarm and a shutdown when a trip point is reached. The sensors are usually installed in pairs on opposite sides of the machine to detect misalignment on either side. Sensors can be connected directly to a PLC input, or for greater safety, to a central independent monitoring system such as 4B’s T500 Elite Hotbus™, Watchdog™ Super Elite or T400N Elite Hotswitch. Inspection doors are available to assist with periodic maintenance and testing of the brass rub block and system.
