OPTOELECTRONIC ELEMENTS OF MEASURING DEVICES AND PRINCIPLES OF CONSTRUCTION

Аннотация

This article discusses primary transducers that are used to obtain information about both the movement and other parameters of liquids, gases and various solids. This article is based on the principles of their operation, as well as the property of transparent liquids, gases and solids, which absorb the light flux passing through them, depending on the wavelength of the radiation flux, layer thickness and composition of the controlled substance.
