Capacitive measuring element for oscillometric measurement of conductance of streaming solutions and method of determining the dimensions thereof

摘要

The invention relates to a capacitive measuring element intended for continuous measurements of conductance in streaming solutions. The essence of the measuring element is that in the measuring space the surfaces limiting it are covered by an electrically insulating material. A method for obtaining the dimensions of the measuring element has also been proposed. According to the measuring element of the invention the measurements of concentration from very low values with high accuracy and low noise level are possible. The life duration and the reliability of the measuring element are high, and it shows a high resistivity against corrosive media to be measured.
