Ultrasonic Lab

Complete Ultrasonic System:

  • Sensors
  • Piezo ceramic, housing, backing
  • Pulse-echo and transmission transducers
  • Microcontroller for data handling, processing and excitation

Measuring Devices:

  • Oscilloscope
  • Band filters
  • Operational amplifiers
  • Pressure and temperature sensors
  • Signal generator 

Analyses and Calibration Software:

  • Spectrum analysis
  • Variant time series analysis
  • Artificial Neural Network (ANN) and Partial Least Square (PLS) calibration models


Bioprocess monitoring (Terinary Mixtures Fermintation):

  • Using appropriate ultrasonic sensor technology and soft sensing principles
  • Applying suitable pattern recognition and chemometrics methods for multivariate calibration

Fouling supervision:

  • Online process monitoring using ultrasonic sensor
  • Differences in signal parameters reflect fouling existence/absence

Dough production processing:

  • The losses in one of the dough production facilities sums up to 50.000 € per year
  • Using acoustic impedance in dough (visco-elastic material) for online estimation of density à reducing loss in dough processing
