Ultrasonic Level Sensor Application :

Accurate measurement of liquid volumes at any point in a container is critical for many commercial and industrial processes. Reducing process variability results in less waste, higher quality and reduced cost, and can make a big difference in profitability for OEMs.which offers a variety of continuous level sensors to address a wide range of applications. One such technology is ultrasonic. Ultrasonic technology should be considered in vented or non-pressurized applications.Ultrasonic sensors work on the basic principle of sound waves (mechanical energy) to determine material level.

The sensor emits a high frequency pulse above human hearing (20-148 KHz). The ultrasonic transducer, in transmit mode, generates a high-pressure sound wave (similar to a loudspeaker) that propagates to a target and then reflects back from the product surface (echo). The transducer then switches to receiver mode (similar to a microphone) to listen for the reflected wave (echo). The reflected wave is then converted to an electrical signal that is converted to give the distance to a specific target.The changing distance to a target is converted to a linear 4mA to 20mA current output to provide continuous level measurement. Ultrasonic sensors can be easily programed, on site via push button programming, or by PC, for different application heights within their range.
