Transducers and transducers of post-sonic frequencies

The transducer or transducer produces an electrical signal under the influence of pressure or some other effects. The electrical resistance of the pressure transducer changes according to the pressure changes, and thus becomes capable of operating a measuring device or other graphic device (271). The very small pressure transducers include elements of silicon crystal that can be equipped with some machines and can be placed in some parts of the body.

The process of detecting cracks with post-sonic waves includes bars of steel or any other material that receive the post-sonic waves above one of its surfaces. These bars can be moved inside a container containing a liquid and the entire device can remain on the objects to be examined. The distance of the crack is determined by the reflection of the post-sonic waves on its other surface or on the internal cracks in it.

273 - Electrolysis by current.
274 - Finding the pH value of the liquid.

The cathode ray tube is used to determine the time period taken for the wave to reflect and thus to determine the location of the crack itself. Signals with a frequency after sonication are used in depth sounding operations, where the depths of the oceans are determined by measuring the time interval between the transmission of an ultrasonic wave from a certain body in the water and the arrival of the reflected echo from the ocean floor (see p. 126).

Electrolysis

There are many electronic methods used in chemical analysis. In electrolytic analysis, the components are chemically separated by passing a certain electric current. When water is electrolyzed, it is divided into hydrogen, which collects on the negative electrode, and oxygen, which collects on the positive electrode (273). The ions that move towards the cathode are called cations, while the ions that move towards the positive electrode are called anions. The decomposed materials may precipitate on the neutral electrodes, and then they are weighed. The acidity of a liquid can be calculated using an acidity-sensitive device that includes two electrodes, one of which is neutral and the other sensitive to acidity, so that it indicates the acidity value present. However, a very sensitive measuring circuit must be used for this purpose (274).
