Ultrasound Transducer, 40 kHz, Equipment Kit Equipment set for experiments on geometric and wave-mechanical acoustics.
Based on the piezo-effect discovered by the Curie brothers, an AC voltage is applied to a piezo-electric body causing it to oscillate. Sound waves can also be used to excite the body and the oscillations can be converted into an electrical voltage signal.
Resonant frequency:           40 kHz approx.
Band width:                           6 kHz approx.
Capacitance:                        1900 pF
Connector:                            BNC
Stand rod:                             150 mm x 10 mm diam.
Dimensions:                         40 mm x 20 mm diam.
