Ultrasonic thickness gauge having automatic transducer recognition and parameter optimization and method thereof

摘要

A measurement system employs a method and apparatus for uniquely tagging each of a plurality of transducers, automatically recognizing the tag for identifying the transducer and automatically adjusting electronic parameters of the system for enhancing performance with a selected transducer. In a preferred embodiment, a resistor is inserted in a piezoelectric transducer of an ultrasonic thickness gauge, a current source and A to D converter measure the resistor and a microprocessor- based logic system adjusts measurement parameters of the gauge to be automatically optimized for the associated transducer characteristics.
