1. a kind of measuring system for being used to measure material thickness, the system include:

  • Measuring probe, it include with longitudinal axis delay block and by the way of active combination is formed acoustical coupling in the delayMultiple element of transducers of block, the active combination include being used to produce the conveyer side of supersonic beam and for reception of echoes signalReceiver-side, the receiver-side and the conveyer side are spaced relationships, and the spaced relationship is formed around described verticalThe gap of axis, the gap are included using making the conveyer side be set with the receiver-side by the way of acoustically separatingCrosstalk barrier;

    WithThe detecting instrument of the measuring probe is coupled in, the detecting instrument includes interface, and the interface is described super using causingThe mode of first parameter of acoustic beam controls at least one element of transducer in the active combination, and the control, which forms first, to be hadSource is combined and the second active combination, the second active transducer of the combination with the quantity different from the described first active combinationElement;

    Wherein, the receiver-side includes at least one element of transducer in response to the echo corresponding to the supersonic beam.
