Shengke SK-WK®Non-Invasive Level Switches: Safeguarding the Safe Operation of Caustic Wash and Oxidation Towers at an East China Nuclear Power Wastewater Station!

Recently, Shengke Electronics' SK-WK® non-invasive level switches were successfully commissioned on the caustic wash and oxidation towers at a nuclear power wastewater station in East China.
Several units are now responsible for the precise monitoring and alarming of high and low liquid levels, while integrating with the PLC control system to automate filling and draining processes.
Built for Rigorous Nuclear Conditions—Zero Safety Compromises!

Shengke's SK-WK® ultrasonic non-invasive level switches are perfectly suited for the harsh operating conditions of nuclear power plants. The SK-WK® sensor probe utilizes an external clamp-on installation, eliminating the need for drilling or hot work on the tower body. Because the sensor does not come into contact with the strongly corrosive alkaline and oxidizing media, leakage and corrosion risks are fundamentally eliminated. Having passed rigorous environmental adaptability testing, the equipment operates stably in high-temperature, high-humidity, and highly corrosive environments, fulfilling the core nuclear power requirements for maximum safety and reliability. Operating on the principle of ultrasonic reflection, the SK-WK® penetrates the vessel wall to accurately capture level changes and deliver precise high and low level alarms. Its advanced anti-interference algorithm effectively filters out disturbances from bubbles and foam inside the tower. This ensures a stable and reliable signal, providing accurate data support for level control in caustic wash and oxidation reactions, while effectively preventing process fluctuations and safety risks caused by level anomalies. The external dual-probe system (for measurement and calibration) is compatible with various materials and installs securely to ensure signal accuracy. It is suitable for carbon steel, stainless steel, hard metals, FRP (Fiberglass Reinforced Plastic), rigid plastics, ceramics, and other composite materials.
