4B Group - Model RB2W4LR2 -Brass Rub Blocks Kit

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.
