Ultrasonic Level Transmitter Working Principle

Ultrasonic Sensors Measurement Principle          Ultrasonic transducers transmit and receive sound waves using piezoelectric components. When a voltage is provided, the piezo components start to vibrate. High-frequency soundwaves are created by this vibration. These impulses are reflected by the target, and an echo is sent back to the ultrasonic transducer. The distance can be determined …
