Abstract:
     This invention charaterized in that an electric resistor whose resistance value is correlated with its length is buried in lining in a direction perpendicular to the lining. The resistor and lining are cynchronously worn and eroded. By measurement of change in resistance value and use of corresponding measurer, the current thickness of lining may be in-circuit tested.
