Цитата:
Ultrasonic transducers are used for a variety of instrumentation and control applications, most commonly for flow measurement, non-destructive inspection of materials, and level measurement.
In general, an ultrasonic transducer is any device capable of converting electric pulses into mechanical energy, producing sound at frequencies above hearing capability. The frequency selection will change with the application. For flow measurement, frequencies can range from 30 kHz to 5 MHz. In level measurement, they can be expected to be lower, usually between 30 kHz and 200 kHz. For inspection equipment, such as thickness gauges and flaw detectors, frequencies can cover larger frequency ranges, but typically are much higher than those seen in the other instruments.
