TRANSDUCER FOR MEASURING electrical capacitance (permittivity) and electrical resistance (conductivity) of liquid or gas

摘要

Transducer for measuring the electrical capacitance (dielectric constant) and electric resistance (electrical conductivity) proposed in this solution will improve the quality of continuous direct control of the properties of liquids and gases. The primary device includes three plate electrodes immersed in a controlled environment, and forming an electrical capacitor, and display electrodes. Two electrodes impact connected with the source voltage. measurement electrode disposed between the electrodes with a gap relative to the impact of these electrodes and connected to the signal converter. Screen electrodes are arranged around the perimeter of each of the electrodes and measuring the effects of the electrode and connected with a voltage source. The parameters of the electric voltage applied to the screen electrode, the shape and relative position of electrodes and measuring the effects of the electrode with the appropriate display electrodes meet the conditions ensure laminar electrical field in the measuring zone. 7 ZP 1 yl.
