Functionality of a piezo ultrasonic atomizer

The VIBRIT® calotte vibrator is incorporated into the base of a liquid reservoir whose level must be kept constant at all times at the focus of the calotte.

The calotte vibrator is driven by a high frequency AC supply and transmits ultrasonic waves which are focused at the surface of the liquid (calotte focus) and produce an ultrasonic "nozzle".

The ultrasonic nozzle discharges very small droplets of the liquid - the aerosol - which can then be used for the required purpose.

The water has to be maintained at a constant level with an accuracy of 5 mm. A float control switch or overflow control can be used for this purpose. The aerosol output can be regulated by an external control voltage or potentiometer.
