Embodiment Construction

[0020] Embodiments of the invention: as figure 1 As shown, it includes a main measuring rod 1 and an electronic unit 2 as the main measuring pole, and an auxiliary measuring rod 3 as an auxiliary measuring pole is installed on the main measuring rod 1, and the auxiliary measuring rod 3 and the main measuring rod 1 form an independent measurement circuit, It eliminates the problem of poor contact of the installation part caused by the vibration of the traditional radio frequency admittance level switch, and solves the measurement error caused by the large vibration of the use environment, improves the reliability of the measurement, and makes the operation of the level switch more stable. more reliable. The electronic unit 2 is composed of an aluminum shell and a circuit board installed in the shell. A power plug and a connecting terminal are arranged on the end of the shell, and a high-frequency circuit, a bridge circuit, a detection amplifier circuit, and a plastic circuit a...

Abstract

The invention discloses a bipolar radio-frequency admittance material level switch, comprising a main measuring staff 1, an electronic unit 2 and an auxiliary measuring staff 3 arranged on the main measuring staff 1, wherein, the auxiliary measuring staff 1 and the main measuring staff 3 are connected with the electronic unit 2. The bipolar radio-frequency admittance material level switch has the characteristics of HF corrosion resistance, high temperature resistance, scouring resistance, electromagnetic interference resistance, static electricity prevention, hanging prevention, anti-strong vibration effect, etc. The invention has stable and reliable operation, low failure rate and long service life, thereby greatly reducing expenses for repairing and maintaining spare parts and reducing cost for manufacturing electrolytic aluminium. The invention saves expenses of spare parts over 500,000 Yuan annually according to a calculation that consumption of material level switches are reduced by 100 per year, thereby providing a considerable economic benefit. The product not only can be applied to material measurement in the aluminium industry, but also can be popularized and applied in the petrochemical industry, the metallurgy industry, the electrical power industry, the energy industry, the cement industry and other industries.

Description

Technical field: [0001] The invention relates to a material level measuring switch, in particular to a bipolar radio frequency admittance material level switch. Background technique: [0002] In the aluminum industry, for the measurement of the material level of the main body of the electrolytic cell, most of them use "resistance-rotary material level switches, capacitive material level switches" and so on. Due to the very harsh environmental conditions in the production process of the electrolytic cell, there are high temperature, high dust, strong electromagnetic field, strong vibration, strong HF gas corrosion, etc., which seriously affect the reliability and service life of the material level switch, resulting in the failure of the material level switch The high rate of damage, large amount of damage, and high cost of production, maintenance and repair seriously restrict the optimization of the technical indicators of the electrolyzer. Invention content: [0003] The ...
