ultrasonic Maksud & Definisi

Contoh ultrasonic

• There were several results about amplitude of ultrasonic signal in air.

• Ten to twenty grains were selected from each sample, washed with methanol in an ultrasonic bath and rinsed with distilled water.

• This ultrasonic treatment is an invasive technique because surface samples have to be cut out from the plant and studied in bath sonicators.

• Ultrasonic inspecting subsystem: it is carried by the robot to detect the flaws and to measure the thickness of the tank surface.

• To apply this technique, a short burst of ultrasonic energy is generated, amplified and transmitted by a transducer.

• The reason for this control simplicity is the additional information about working areas provided by the ultrasonic system in addition to numerical ranges.

• Among these techniques, ultrasonic systems have attracted much interest because of their low cost and potentially good accuracy for distance measurement.

• Despite their simple and accurate range measurement, use of ultrasonic transducers in map building is plagued by a few shortcomings.
