A multi-array adaptive capacitance tomography sensor device belongs to the detection field. Including an empty insulating container, a multi-array electrode plate, an insulating layer and a shielding layer; the outer surface of the empty insulating container is fixedly connected with a multi-array electrode plate, and the outer layer of the multi-array electrode plate is an insulating layer and a shielding layer; the multi-array electrode plate It consists of multiple annular plate groups arranged at equal intervals along the axial direction from top to bottom, and each annular plate group is composed of multiple uniformly distributed unit plates; through the physical on-off control of the unit plates, Composite plates of different sizes can be formed. When the non-metallic mixture to be measured is placed in any position of the container, the position of the object to be tested is judged by the layer-by-layer detection of the multi-array adaptive ECT sensor, and the number of measuring plates, geometric dimensions, and axial shielding are selected according to the actual measurement requirements. And other parameters, so that the sensor always maintains a good measurement effect.
