¿ What is Ultrasound?

The sounds generated above the perceptible range by the human ear( tipically20 kHz) are called ultrasound.Even though the ultrasound his behavior is like the audible sound, it has wavelength much less.

¿WHAT IS A SOUND TRANSDUCER?

A transducer is a device that transform a way of energy in other. A sound transducer turn Electric energy into mechanic energy, in a way of sound and the opposite. The principals components are the active element , the support and protector surface.

The Active ElementIs a ferroelectric material it turn the electrical energy into a pulse of excitation in Ultrasonic energy.The materials used commonly are polarized ceramics that are cuts in many ways to produce Many different ways of wave.

The SupportThe support is usually a strong attenuator, a material of hight density used to control theVibrations of the transducer absorbing the radiated energy by the back face of the active element. 

EXAMPLES AND APPLICATIONSMeasurer of levels and detections of objects.The ultrasounds are very practical to measure levels Of materials where other sensor cant work, like in environment with dust or steam, or Even transparent objects, where the photoelectric sensors cant work. So can be used to measure sand silos to determinate the height of liquid in Deposits or calculate the height of different objects.
