Mounted Piezo Transducer

A mounted Piezo Transducer, consisting of a 15mm diameter ceramic element with integral, protective press-stud. The device gives voltage pulses of up to 20V when given a sharp tap. Useful to demonstrate mechanical to electrical energy conversion with a voltmeter, data-logger or oscilloscope. The reverse effect can also be shown by connection to a signal generator whereby the device converts the electrical signal to sound waves.
