What Sensing Objects Are Hardly Detected By The Ultrasonic Displacement Sensors And The Ultrasonic Sensors?
Since objects with extremely high sound absorbency (sound absorbing materials such as fresh snow and glass wool) do not produce reflected sound, they may not be detected.
Moving objects
(1) When detecting the liquid level which is waving or being agitated, the waving liquid level is directly detected.
(2) Objects moving at high speed (vehicle on expressway, motorcycle and etc.)
High-temperature objects
Surrounding air is heated so that ultrasonic waves may be reflected.
