Slide 7: Working Principle
Working Principle Ultrasonic sensor disks are ceramic disks which are using the piezoelectric effect to emit and to detect inaudible sound waves. This property can be used in gases and liquids for various applications like obstacle detection, distance measuring, flow metering, and level sensing.
Slide 8: Dynamic Behavior of Free Disk Resonance Modes: Radial & Thickness
Dynamic Behavior of Free Disk Resonance Modes: Radial & Thickness Due to frequency-dependent sound absorption in air, ultrasonic frequencies used in air applications must be significantly lower than those used in liquids. A single disk can vibrate in Radial mode Thickness mode two primary directio
