Ultrasonic Distance Sensors Applications with Piezo-ceramic Components


A piezo-ceramic disc sends a short ultrasonic air wave in the direction of the object whose distance is to be measured. The sound wave is reflected by this object and received again by the same piezo-ceramic part. The piezo-ceramic part operates here as sender and receiver (time multiplex mode). The piezo-ceramic part normally has an adaption layer on the radiating side to match the acoustic impedance of the transducer to that of the air. The frequency used by the transducer (resonance mode) here depends on the desired range and the resolution. The higher the frequency, the higher the resolution and the shorter the range, and vice versa. If the wavelength resulting from the frequency is large in comparison to the size of the transducer, the result is a spherical-shaped radiation of the wave front. If the wavelength is shorter than the transducer, it is radiated straight (in a close angle). Directed radiation is desired in almost all cases. The distances that can reasonably be measured using these systems are between 0.25 m and 10 m. This application can be used for a variety of purposes in industrial automation, for example, for distance measurement, as a limit monitor or as a counter (an object is registered every time it passes through the measuring range).
