Abstract
The invention refers to an ultrasonic measuring means exhibiting improved stability and calibration adaptability. Ultrasonic energy signals are transmitted into a workpiece and echo responsive signals are received therefrom. A timing signal having a pulse width commensurate with the workpiece thickness is generated. The pulse width is measured by a time interval averaging circuit in combination with a programmable counting means for adjusting the quantity of time interval average measurements required for determining the thickness of the workpiece. The programmable means is adjusted to a value commensurate with the acoustic velocity of the workpiece for causing the output of the apparatus to display the dimension of the workpiece measured.
