Inductive electrode is a measuring device designed for strong corrosion, high temperature and high pressure scenarios, with the core advantages ofNot in direct contact with the tested solutionBy using a built-in induction coil to capture the potential difference generated when the solution flows through, precise conductivity measurement can be achieved. Its installation needs to revolve around three core areas: flow type tee layout, material selection, and pipeline adaptation.
Basic installation formUsing a circulating tee as the installation carrier, it is necessary to meet the following requirementsInner diameter of pipeline ≥ 65mm(Ensure stable and accurate measurement). If the inner diameter of the pipeline on site is small (such as 25mm, 50mm), it needs to pass throughVariable diameter designExpand the diameter of the middle measuring section (such as changing the diameter of a 50mm pipe to 100mm), place the induction electrode in the expansion section, ensure that the solution flows smoothly through the coil, and avoid affecting data accuracy due to narrow pipelines.
Three way production methodOn site conditions allow for self production; If there are no conditions, provide pipeline dimensions (such as 25mm, 50mm) and material information, and customize three-way fittings to reduce on-site construction difficulty.
Inductive electrodes are available in three core materials: PP, PFA, and PEEK. The selection should be based on the corrosiveness, temperature, and pressure of the tested solution
pressure resistanceConventional can withstand pressures of over ten kilograms, meeting the measurement requirements of industrial pipelines;
temperature resistancePEK material is commonly resistant to high temperatures of 100-200 ℃. If measuring high-temperature solutions, a "sensor high temperature resistance+external digital chip" design is adopted (the chip is placed in a non high temperature area to avoid temperature transmission) to avoid damage to the chip due to high temperatures.
Due to its non direct contact with the solution and corrosion and high temperature resistance, induction electrodes are mainly used in two types of scenarios:
Measurement of Strong Corrosion SolutionsAcidic and alkaline solutions used in the chemical and electroplating industries to prevent electrode corrosion and failure;
Measurement of High Temperature and High Pressure SolutionsIndustrial high-temperature liquids, such as those used in power plants and pharmaceutical industries, with temperatures ranging from 100-200 ℃, can be stably measured through an external chip design.
Overall, the installation of induction electrodes should prioritize matching the pipeline size (with necessary diameter changes), selecting the right material, and adjusting the chip position according to the working conditions to ensure accurate and long-term conductivity measurement in complex industrial environments.
