The ceramic alumina electrode RDJ-2000 used in the boiler water level gauge of the power plant has excellent corrosion resistance when soaked in water or steam for a long time. You know, this electrode works in a harsh environment, just like a soldier on the front line, and must withstand pressure and loneliness. Next, let’s talk about the corrosion resistance of the RDJ-2000 electrode and see why it is so awesome.

The RDJ-2000 electrode is a small part used in the boiler water level gauge of the power plant, but don’t underestimate it, this thing is the eyes and ears of the entire water level control system. In a high temperature and high pressure environment, it must accurately feedback water level information to help operators monitor the boiler status in real time. To achieve this, the corrosion resistance of the electrode is the key.

The magic of ceramic alumina

The core material of the RDJ-2000 electrode is 99.9% high-purity alumina, which is not an ordinary material. High-purity alumina ceramics have extremely high chemical stability and hardly react with water, steam, acid and alkali solutions. Even in a high pressure and high temperature environment, they maintain stable physical and chemical properties. This means that even if the RDJ-2000 electrode is soaked in water or steam for a long time, it is not afraid of corrosion and can maintain good insulation performance and mechanical strength.

The water and steam in the boiler are not fuel-efficient. They contain various minerals and impurities. With high temperature and high pressure, it is simply purgatory for ordinary materials. But for the RDJ-2000 electrode, these are nothing. The corrosion resistance of high-purity alumina ceramics allows the electrode to maintain a stable working state in harsh environments, ensuring the accuracy and reliability of water level measurement.

In addition to corrosion resistance, the insulation performance of the RDJ-2000 electrode is also excellent. The insulation performance is >500MΩ, which means that when the electrode works in a conductive medium, it can effectively prevent current leakage and protect the circuit from being affected. This is crucial to ensure the normal operation of the water level meter and the safety of the operator.

The test of long-term immersion

In actual applications, the RDJ-2000 electrode often faces the test of long-term immersion. Whether it is the start-up, shutdown, or daily operation of the boiler, the electrode must stay steadily in the water or steam to accurately feedback the water level information. Thanks to the excellent properties of high-purity alumina ceramics, the RDJ-2000 electrode can withstand long-term immersion, maintain structural integrity and functional stability, and become an indispensable part of water level control.

In summary, the reason why the RDJ-2000 electrode can maintain excellent corrosion resistance when in contact with water or steam for a long time is attributed to its core material – 99.9% high-purity alumina ceramics. The chemical stability, mechanical strength and insulation properties of this material enable it to work stably in harsh environments of high temperature and high pressure, providing a solid guarantee for the accurate measurement of boiler water level.
