Cathodic protection potentiostats are key equipment in cathodic protection systems. Their related features and functions include multiple outputs, AC power supply, corrosion control, engineering-specific applications, and support for OEM services.

Multiple outputs: Some potentiostats feature multiple output channels. For example, the CPMS potentiostat has three outputs. They can provide cathodic protection to multiple protected objects simultaneously or control different parts of the same protected object separately, enhancing protection effectiveness and flexibility. Multiple units can also be connected in parallel to expand output current, meeting the protection needs of large-scale projects such as long-distance pipelines.

AC power supply: Potentiostats are typically powered by AC power. Common power specifications include single-phase 220V±10%, 50Hz±5%, or three-phase 380V±10%, 50Hz±5%. They can adapt to a certain range of grid voltage fluctuations to ensure normal operation of the equipment.

Corrosion control principle: Potentiostats operate based on the negative feedback control principle, forming a closed-loop regulation system with the protected object. By measuring the potential at the energization point using a reference electrode and comparing it with the control signal, the potential controller adjusts the power supply's output voltage or current when the potential deviates from the set value. This changes the polarization current, restoring the protected object's potential to the set value and inhibiting corrosion reactions.

Engineering-specific features: These systems are suitable for impressed current cathodic protection of metal structures such as steel pipelines, cables, steel pile docks, ships, and tank bottoms in various environments, including soil, seawater, and freshwater. They are also used for anti-corrosion protection of underground or underwater steel structures in industries such as petroleum, petrochemicals, natural gas, and power. They offer multiple protection functions, including overcurrent protection, lightning protection, and overheating protection. Some models may also feature RS-485 MODBUS digital communication for remote monitoring and centralized management, meeting the requirements of complex engineering environments and long-term stable operation.

Support for OEM services: Some manufacturers in the market offer OEM services. For example, Henan Bangxing Anticorrosion Material Co., Ltd.'s cathodic protection potentiostats support processing and customization. OEM manufacturers can produce potentiostat products according to specific technical requirements and specifications based on customer needs, helping clients quickly launch equipment that meets their business requirements while saving on R&D and production resources.
