Description

Technical Field

[0001] The utility model relates to an industrial electrode, in particular to an industrial electrode with a novel anti-interference structure. Background Art

[0002] When testing online electrodes, they are often affected by electromagnetic interference from other devices in the environment, resulting in unstable values, inaccurate readings, and other situations. In general, try to keep the instrument away from devices or areas where electromagnetic interference may occur, such as motors, inverters, and high-power electrical appliances. If these areas cannot be avoided, it is generally recommended to add metal shielding or isolation equipment to the instrument. When the instrument is subjected to anti-interference treatment, the industrial electrode is generally also subjected to anti-interference shielding treatment.

[0003] Generally, the shielding of industrial electrodes is more about shielding the wires and joints, and less about shielding the electrode body. The shielding of the electrode body is generally done by using a metal shielding cover on the inner wall of the electrode to prevent interference with the industrial electrode. Or, using the dual-electrode method, an auxiliary electrode is added to the measuring electrode to achieve the effect of electrode anti-interference. Using a metal shielding cover to shield the inside of the electrode requires seamless connection between the shielding cover and all the transition structures, otherwise it will affect the shielding effect and cannot achieve a good anti-interference effect. The dual-electrode method has a complex processing technology and high cost, and most industrial electrodes are not suitable for this processing technology. Summary of the invention
