ABSTRACT:
Apparatus for measuring the sidewall thickness of cylindrical articles during in-process ram and die drawing, inclined axis multiple polar sensors induce eddy currents by means of the angular motion of a rotating magnetic field, the signal phase angle representing sidewall thickness, also ram and die centering signals generated. Inclined axis polar sensors also measure both cylindrical and flat article hardness by phase shift.
