Abstract

The invention discloses a combined printing circuit board electric capacitance tomography sensor in the field of design of sensors. The sensor consists of one or more measuring electrode modules; each measuring electrode module is in a three-layer printing circuit board structure and comprises an inner plate, an electrode array plate and an outer plate; the inner plate forms the inner wall of a measuring channel; a substrate made of nonconductive material is arranged in the middle of the electrode array plate; the outer plate forms the outer side of the sensor. The sensor provided by the invention can be arranged on the outer side of a flowing channel on the wall surface of a non-conductor in a conventional manner, and also can be arranged on the inner wall of the flowing channel, so that the material and structure of the original pipeline are not changed; meanwhile, the sensor has the characteristic of thin wall, and the influence on flowing can be reduced to the minimum when the sensor is arranged on the inner wall of the flowing channel.

Description

technical field [0001] The invention belongs to the field of sensor design, in particular to a combined printed circuit board capacitance tomography sensor. Background technique [0002] Matter can have different forms, such as liquid, gas, etc., or the same physical form but different components, such as oil and water. When two or more substances with different forms, or substances with different components flow in the pipeline at the same time, the measurement of the position distribution and concentration distribution of one or more substances on the pipeline section is common in industrial applications. The problem. Ideally, it is not desirable for the sensor to intrude too much into the flow area to cause disturbance to the flow; at the same time, it is hoped that a complete cross-sectional material distribution can be obtained. However, such measurements are often difficult due to the complexity of the material distribution and its variation with various conditions. ...
