Радіочастотний сенсор каламутності рідких середовищ

Abstract

The invention relates to inspection technology. The radio-frequency sensor of turbidity of fluid media includes a transistor circuit, three resistors, five capacitors, the first and the second primary measuring converters connected in parallel, common bus and power supply bus. At that the first resistor is connected to the common bus, the first capacitor – to the power supply bus, the second primary measuring converter is connected to the second capacitor. According to the invention, additionally there are included the second common bus and antenna, at that as the primary measuring converters resistive primary measuring converters are used, and as transistor circuit a unijunction transistor is used. The emitter of the unijunction transistor is connected to the second resistor and the third capacitor, this is connected to the antenna and the fourth capacitor, this is connected to the fifth capacitor, the first common bus and the first resistor connected to the fifth capacitor and the first resistive primary measuring converter. At that the first base of the unijunction transistor is connected to the second capacitor and the third resistor, this is connected to the second resistor and the first capacitor connected to the second common bus. The second base of the unijunction transistor is connected to the first resistive primary measuring converter, and the second resistive primary measuring converter is connected to the first resistor and the first common bus. The sensor provides increase of sensitivity, simplification of construction and enhancement of functionality.
