Ultrasonic Level Sensor Working Principle

The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound.

Ultrasonic level sensor working principle.

An ultrasonic sensor can convert electrical energy into acoustic waves and vice versa. Ultrasonic sensor working principle ultrasonic sensors emit short high frequency sound pulses at regular intervals. Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The ultrasonic sensor or transducer works on the same principles as a radar system.

The ultrasonic level sensor s working principle ultrasonic level sensors use the time of flight measuring principle to measure level. The normal ultrasonic wave frequency is between tens of khz and tens of mhz. Ultrasonic wave is more than 20khz infrasonic wave is less than 20hz. These waves bounce from the surface of the product creating an echo that goes back to the sensor.

Ultrasonic level transmitter is continuous level measurement in liquids and solids with ultrasonic level sensors ultrasonic waves detect an object in the same way as radar does it. These propagate in the air at the velocity of sound. The ultrasonic device sends sound waves at a frequency higher than a humans can hear from 20 kilohertz to one gigahertz. This pulse travelling at the speed of sound is reflected back to the transmitter from the liquid surface.

Ultrasonic uses the sound waves and radar uses radio waves. Ultrasonic level sensor working principle. Ultrasonic level sensor s working principle ultrasonic level sensors use the time of flight measuring principle to measure level. How it works level measurement ultrasonic level transmitter working principle an ultrasonic level transmitter is mounted on the top of the tank and transmits an ultrasonic pulse down into the tank.

Our ultrasonic sensors like many others use a single transducer to send a pulse and to receive the echo. The acoustic wave signal is an ultrasonic wave traveling at a frequency above 18khz.
