I. Introduction to Corrosion Monitoring
Corrosion monitoring is a crucial aspect of maintaining the safety, reliability, and longevity of equipment and pipelines in the petrochemical industry. A deep understanding of this process helps to prevent failures, mitigate risks, and increase overall operational efficiency. Over the years, the technology used for corrosion monitoring has evolved significantly, with newer systems providing more accurate and real-time data.
II. The EMT-CP-0 Resistance Corrosion Online Detection System
The EMT-CP-0 is a state-of-the-art system designed for corrosion monitoring. It works by keeping track of changes in the resistance value of the corrosion probe’s sensitive parts and figuring out how much corrosion is thinning those parts. This system is built on the principle that the material of the corrosion probe’s sensitive elements should match the material of the pipeline or equipment. The calculation of the corrosion rate over time allows for online monitoring of the pipeline or equipment.
A key benefit of the EMT-CP-0 system is its explosion-proof structure, making it an ideal choice for the petrochemical industry where safety is paramount.
III. The EMT-CP-0 Remote Data Collection
The EMT-CP-0 system includes a remote data collection component composed of various modules such as power supply, measurement and control logic, and data transmission. These modules work together to gather and process information efficiently. The system is configured based on an ID provided at the time of manufacture, enabling it to enter into a normal operating status. The ID-based configuration simplifies the setup process and ensures that each system is uniquely identifiable, supporting more precise data tracking and analysis. Additionally, the modular design of the EMT-CP-0 system allows for easy maintenance and upgrades, further enhancing its longevity and reliability in the field.
IV. Signal Transmission in the EMT-CP-0 System
The EMT-CP-0 system uses two methods for signal transmission. The first involves two wired forms, with a working power supply of DC24V provided on-site and an output of RS485 signal or 4-20 mA. The second method is a wireless form using Bluetooth technology. This form uses its lithium battery as a power supply, storing the collected data in internal storage and downloading it through an explosion-proof Bluetooth device. Each method has its advantages, and the choice between wired and wireless forms will depend on specific site conditions and requirements.
V. Technical Advantages of the EMT-CP-0 System
One of the key technical advantages of the EMT-CP-0 system is its weak relationship to the medium. This characteristic allows it to measure the corrosion of various phases of media, including liquid, gas, and mixed media. This versatility enhances the system’s effectiveness in diverse operating conditions.
VI. EMT-CP-0 System Performance Parameters
The EMT-CP-0 system has a wide range of performance parameters. The impedance range of the probe-sensitive element is between 1 and 50 mΩ, with a typical resolution value of 1nm. The system operates on a 24VDC power supply or a lithium battery and has a current consumption of 12mA@24VDC/1~12mA@8.4V.
The system employs several communication systems, including RS485 two-wire with a 2400 baud rate, 2.4G, LORA, 4G/5G, or 4-20mA. It can operate in a broad temperature range from -40°C to +70°C and has an enclosure protection level of IP 65. The data collection rate can vary from once per minute to any interval, based on the needs of the operation.
