Комплект по исследованию ультразвукового измерительного датчика-преобразователя с частотой 40 кГц

Описание товара

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.



Contents:

1 Ultrasonic transmitter, on stand rod

1 Ultrasonic receiver, on stand rod
