  text: For many applications like level measurement and industry robotics it is of
    advantage if the directional characteristic of an ultrasonic transducer is changeable
    or adaptable for the improvement of spatial resolution. Often this goal is reached
    with the use of ultrasonic transducer arrays, which elements are driven with phase
    shifted excitation signals. One disadvantage of these solutions is the great effort
    for building such an array and the multi-channel sensor electronics. In this contribution
    the directional characteristic of a single air transducer with segmented electrodes
    is analyzed. Therefore a variable script based finite element model is used to
    discover the influence of different electrode configurations on the directional
    characteristic of a single piezoceramic transducer. Especially the influence on
    the angle of beam and the near field length are evaluated. The used variable model
    permits an optimization of the configuration with regards to the mentioned criteria.
    The findings will be used for the development of a level measurement system for
    bulk solids.
