What is the frequency of piezoelectric?

The most commonly used piezoelectric crystals are AT-cut quartz crystals with a certain resonant frequency (9 MHz, 27 MHz).

What is the range of piezoelectric transducer?

Piezoelectric force sensors should have an operating temperature range from -50 to 350 ºC and should have sensitivity of approximately 105 pC/N. Piezoelectric pressure sensors should have rise time less than 2.0 micro seconds.

How do you test a piezoelectric disk?

Apply a small voltage to the piezo from a signal generator, maybe around 1 kHz. If you can hear something, then the wires are connected. A few Volts should be good enough, and won't damage the piezo, especially one that size.
