Experimental Method of Ultrasonic Sensor for Ions and Solutions Discrimination and Identification
The ultrasonic wave or vibration causes the deformation of the medium such as process of forming weld during construction of metallization contacts in semi-conductors. From that we propose to build a special circuit using ultrasonic sensor to discriminate mediums and materials. The spread of wave made by multipath limits the transmission speed. Generally, if the delay spread is the bigger so velocity is low. Thereon, we study the influence of ions in various solutions on the pressure by result on the directivity of ultrasonic wave. Each chemical solution has its appropriate properties that affect ultrasonic wave pressure according to the compression and dilatation of the medium. The goal of the current work is determination of ultrasonic velocity by result identification of chemical solutions. Above that the used method permit to propose an approach that permit to predict the ultrasonic wave velocity and the matching impedance of a mixture of mediums referring to their chemical composition.
