Abstract
A coal pulverizer monitoring system and method measures a displacement of wheels in a vertical roll wheel pulverizer using strain gauges bonded to tension rods in an ambient environment outside the hostile environment of the milling area of the pulverizer. Signals from the strain gauges reflecting strain on the tension rods are converted to a displacement of the wheels inside the pulverizer, and thus a coal bed height.
