Abstract
The utility model relates to an interdigital electrode, and specifically relates to an interdigital electrode applied in a single-electrode capacitance sensor. The interdigital electrode comprises a group of electrode couples. Each electrode couple consists of two pieces of electrodes, and the two pieces of electrodes are marked as Ax and Bx respectively, and x is larger than 0. The electrodes Axs and Bxs are alternatively arranged, the electrodes Axs are electrically communicated with each other, the electrodes Bxs are electrically communicated with each other, and a gap is reserved between each electrode Ax and each electrode Bx. A capacitance sensor with a single rod structure is adopted, and the inside of the sensor is provided with the interdigital electrode, and therefore a problem of jamming is solved well. The interdigital electrode applied in the single-electrode capacitance sensor is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of interdigited electrode, is specifically related to a kind of interdigited electrode that is applied in the single electrode capacitive transducer.
Background technology
The single electrode capacitive transducer needs many electrode forms with coaxial configuration when measuring non-conductive medium, when measured medium too thickness can cause obstruction, influence the measurement of sensor, can't normally use.At this moment the capacitive transducer that adopts the single pole structure is with regard to reasonable the addressing this problem of ability, and interdigited electrode just is applied in this occasion.
Summary of the invention
The utility model problem to be solved provides a kind of interdigited electrode that is applied in the single electrode capacitive transducer, adopts the capacitive transducer of single pole structure, is difficult for during measurement stopping up.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of interdigited electrode that is applied in the single electrode capacitive transducer; Said interdigited electrode comprises one group of electrode pair; Every pair of electrode is made up of two plate electrodes; Two plate electrodes are designated as
and
respectively; X＞0; Said
and
alternately arrange; Mutual electric UNICOM between
; Mutual electric UNICOM between
, the gap of leaving between
and
.
Said electrode can be produced on the flexible insulation substrate, and the flexible insulation substrate is rolled in an insulated pipe outer wall outward.
The utility model adopts the capacitive transducer of single pole structure, and the set inside interdigited electrode has well solved blockage problem, and the utility model is simple in structure, and is easy to use.
