Abstract

The invention belongs to the field of non-contact measuring devices, and provides a unipolar capacitance sensor and a connector device. The unipolar capacitance sensor comprises a measuring electrode, an equipotential ring, a shielding ring and an insulating ring; The measuring electrode, the equipotential ring and the shielding ring are all of a stepped structure, are coaxial and are sequentially assembled from inside to outside; and annular grooves are formed in the same horizontal height of the measuring electrode, the equipotential ring and the shielding ring and are opposite in pairs, and an insulating ring fixed in the radial direction is arranged between any two opposite annular grooves. The connector device adopts a shell layer, a shell layer wire seat, an equipotential layer, an equipotential layer wire seat and a measuring layer to realize good conduction between three conductive layers of the cable and the unipolar capacitance sensor.

Description

technical field [0001] The invention belongs to the field of non-contact measuring devices, in particular to a unipolar capacitive sensor and a joint device. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the rapid development of modern industrial technology, many high-end precision equipment and manufacturing and processing technologies have put forward higher requirements for precision detection technology. High-precision measurement of small displacement, vibration, and small angle changes is becoming more and more important in the field of modern precision instruments. Among them, the capacitive displacement sensor has the advantages of good dynamic characteristics, high resolution, high precision, and good stability, and is very suitable for high-precision, non-contact dynamic measurement. Therefore, it has been widely used in...
