ABSTRACT:
An apparatus and method for measuring the gap, tram, deflection, and wear of rotating grinding plates wherein inductive sensors are mounted in a recessed manner inset from the surface of a first grinding plate and located opposite recessed non-wear surfaces of a second grinding plate, thereby providing data by which plate gap and plate wear may be derived. A plurality of such sensors provide data by which plate tram and/or deflection may be deduced.
