  text: When performing measurements, the effects of the measurement system itself
    on the measured data generally must be eliminated. Consequently, those effects,
    i.e. the system’s dynamic behavior, need to be known. For the piezo-composite
    transducers in an ultrasonic transmission line, a model based approach is used
    to describe their dynamic behavior and take into account its dependence on the
    environment temperature and the acoustic impedance of the target medium. Temperature-dependent
    model parameters are presented, which are obtained by performing a multiplepart
    identification process on the transducer model, based on electrical impedance
    measurements [1]. The identification process uses an inverse approach for optimizing
    a subset of the model parameters. Additionally, algorithmic differentiation methods
    are used to determine accurate derivatives. In a final optimization step, impedance
    measurements taken at different temperatures are used to determine the temperature
    dependencies of the model parameters. These can then be used to assess the plausibility
    of the identification results. Additionally, the parameters can be expressed as
    polynomials in the temperature to take different operating conditions into account.
