Description
Mounted on a test station, the RM4210 measures induced AC voltage, AC current, and associated current density. It also measures DC voltage, DC current, instant-off and current flowing through a decoupling device. These measurements are automatically uploaded to Bullhorn Web via satellite communication. Once uploaded, you can easily monitor them and use them to design andoptimize your AC mitigation systems.
Located at coupon test stations, it measures the induced AC voltage, AC current, and associated current density that can be present on pipelines that are co-located with high-voltage AC power lines. The RM4210 uploads these measurements via satellite to Bullhorn Web, a web-based asset manager, so you can diagnose AC current issues, monitor them over time, and optimize your AC corrosion mitigation systems.
Remote monitoring for:
Feature | Benefit |
Test station cap form factor | Easy to install and maintain, simply latch and unlatch as needed. No separate antenna to mount. |
One percent of reading accuracy | Extremely accurate current and voltage measurements |
Long lasting battery | Reduced maintenance costs and visits to the unit |
Alerts when current density exceeds thresholds | Avoid incidents and prevent corrosion due to AC current |
Measurement frequency up to every quarter hour | Easily troubleshoot issues and identify cause of AC current |
Customizable AC monitoring graphs and reports | Show effectiveness of mitigation and easily drill down on trouble areas |
10 MΩ impedance | Improved pipe-to-soil accuracy where just a few mA can be the difference between being in compliance and not |
Flexible reporting | Easily generate reports and hone in on trouble areas quickly |
Mobile configuration and setup application | No need to carry a laptop into the field to set a unit up, do it right from your mobile phone |
Queued two-way communication | Poll, reconfigure, modify reporting schedules, set alarm thresholds and update firmware over-the-air. Communication to the RMU is queued in Bullhorn Web and is sent the next time the unit wakes up to transmit |
Sends alarms based on specific events (e.g. reading out of range, power loss, etc.) | Receive unlimited notifications via text message, email, and voice |
Configurable over-the-air via Bullhorn Web |
|
Bullhorn Web system communicates unit status by email, text, or Web notifications |
|
More than 6.6 kV built-in surge protection per IEC 61000-4-5 specifications | Increase product reliability with immunity to lightning and other surges |
