Embodiment 1
[0036] Such as figure 1As shown, this embodiment provides a capacitively coupled non-contact conductivity measurement device with a wide range of shiftable gears, including an insulating measurement pipeline 1, an excitation electrode module 2, a receiving electrode module 3, an AC excitation source 4, and a voltage detection module 5 , a control unit 6, a receiving electrode analog switch 7 and an excitation electrode analog switch 8. The excitation electrode module 2 is installed at one end of the insulated measurement pipeline 1 , and the receiving electrode module 3 is installed at the other end of the insulated measurement pipeline 1 . The common end of the excitation electrode analog switch 8 is connected to the AC excitation source 4; the channel end of the excitation electrode analog switch 8 is connected to the excitation electrode module 2 installed on the outer wall of the insulating measurement pipeline 1; the channel end of the receiving electrode analog switch 7 ...
Embodiment 2
[0056] The basic structure and principle of this embodiment are the same as those of the first embodiment, the difference is that the excitation electrode module 2 has only one excitation electrode, and the reception electrode module 3 uses three reception electrodes. The receiving electrode is arranged on one side of the exciting electrode, forming a semi-nested electrode arrangement. Only one receiving electrode is in the working state at any time, and the control unit 6 controls the receiving electrode analog switch 7 to switch on different receiving electrodes to realize gear switching. The receiving electrode and the excitation electrode of the electrode form a higher gear, and the number of receiving electrodes is the number of gears. The length of each receiving electrode in the electrode module is the same, and is also the same as that of the excitation electrode.
[0057] The measurement process of this embodiment is:
