Frequently Asked Questions

Ultrasonic Sensor Topic: Resonance

 

FAQ No. FAQ01374

 

Question

 

What is resonance of Ultrasonic Sensors?

 

 

Answer

When an electrical signal is applied in pulses at a frequency close to the resonance frequency of the oscillator, even after the electrical signal has stopped, the ultrasonic vibration remains.

This is called resonance.

For a Reflective Sensor, if this continues for a long time, detection becomes impossible.

 

Pulse, intermittent oscillation and waveform of ultrasonic vibration.
