Intelligent Carbon Steel Test Pile Pipeline Corrosion Protection Potential Cathodic Protection

Detailed Description:

Outdoor Solar-Powered Intelligent Test Station

Application Scope:

(1) Cathodic protection current and potential data collection, transmission, analysis, and management for buried long-distance steel pipelines, metal structures, station valve chambers, and large oil storage tank areas;

(2) Timely and accurate data collection, transmission, analysis, and management for pipeline sections passing through remote or strictly controlled areas, sections with severe stray current interference, and crossing sections.

Product Features:

(1) The product software uses a BS architecture, with built-in terminals, and information can be shared with authorization;

(2) Supports wireless and nano-optical cable transmission for automatic data collection;

(3) The program includes an internal error correction system, and the hardware features a self-wake function in case of system freeze. The data collector meets the requirements for buried or outdoor installation, with a self-cooling method and an operating temperature range of -25°C to +55°C;

(4) The data collector's power supply system uses long-life disposable batteries with a total capacity of 30Ah or a solar power supply system, ensuring continuous operation for up to 20 years;

(5) Lightning surge protection function: Maximum discharge current greater than 60kA. The device can operate normally after withstanding a 15kV instantaneous (20μs) DC high voltage at the input end;

(6) AC interference resistance: Equipped with filtering functionality, it can operate normally under AC interference voltages below 30V.

(7) The product software can share databases with SCADA systems and provides data collection ports.
