Title:
流れ媒体中の伝導率分布を測定する格子センサ及びそれらの測定信号を得る方法
Document Type and Number:
Japanese Patent JP4090077
Kind Code:
B2
Abstract:
A measurement device is disclosed for measuring the conductivity distribution in liquids or multiple phase media flowing in any direction. A grid sensor has electrodes shaped as parallel electroconductive grid bars or wires located in two or three planes and electrically insulated from each other and from their mounting. The electrodes in the individual planes are mutually offset by preferably 90°. One of the planes, the middle plane when three planes are used, forms an exciter plane connected with a pulse generator, whereas the other planes(s) form receiver plane(s) coupled to processing electronics. in the disclosed signal generation process, the electrodes of the exciter plane are successively driven with a symmetrical bipolar rectangular pulse, and all non-driven electrodes are connected with low impedance to the zero potential.
