Ultrasonic Pulse Generator

Ultrasonic Pulse Generator
Control unit for conducting ultrasonic Doppler experiments using 2 MHz
ultrasonic converter (U10016). Includes measurement and evaluation
software for Windows operating system.
If the radiated waves are reflected or scattered from moving particles or
bubbles in fluid flow, the Doppler shift in frequency can be detected. The
equipment detects the scattered waves and generates an audio signal at a
volume that reflects the amplitude of the reflected signal and a frequency
that reflects the speed of the scattering. At the same time, the amplitude is
also displayed on an LED bar display. Sensitivity and volume can be
adjusted by means of appropriate controls.
The controller can also pass on data to a PC for detailed recording and
evaluation. During measurement the current LF Doppler signal is displayed.
Evaluation is by means of a Fourier transformation in the frequency
domain and the result can be interpreted as the distribution of velocity
within the flow.
