Rub Block Kit (inspection door mount with NTC, RTD, or 4-20 mA sensor)

APPLICATION
Detects belt tracking and alignment problems on bucket elevators and conveyors. 

METHOD OF OPERATION
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.
