MOBILTEX
CorTalk RDL1 – Remote Data Logger
SKU: CORTALKRDL1
Capture transient AC and DC interference with high-speed data logging, full RMU1 monitoring capabilities and optional GPS-synchronized interruption with the INT1.
The MOBILTEX CorTalk RDL1 combines stationary data logging with remote monitoring unit (RMU) functionality to provide detailed insight into cathodic protection (CP) system performance. Its enhanced fast-sampling capabilities capture dynamic AC and DC interference for diagnostic analysis, with data transmitted to the CorView Cloud Platform through LTE-M cellular connectivity. For applications requiring interruption, the RDL1 can be paired with the INT1 to provide GPS-synchronized interruption of critical bonds and sacrificial anodes, helping eliminate the need for portable interrupters during close interval surveys (CIS).
Product variants: RDL1
Key Benefits
- Capture transient interference: Enhanced fast-sampling records dynamic AC and DC events that may be missed by conventional monitoring.
- Access remote system data: Cellular connectivity sends measurement data to the CorView Cloud Platform for visualization, analysis and reporting.
- Combine monitoring and data logging: Full RMU1 functionality and fast-sample logging provide both routine monitoring and detailed diagnostic data.
- Add synchronized interruption: Pair with the optional INT1 to provide GPS-synchronized interruption for critical bonds and sacrificial anodes, reducing the need for portable interrupters during surveys.
- Support long-term monitoring: Battery-powered operation supports extended deployment, with typical battery life depending on sampling frequency and interruption activity.
- Simplify field installation: Compact, weather-resistant design fits inside a standard CP test station, with configuration available through a compatible iOS or Android device.
- Expand monitoring as needed: Supports multiple predefined measurement configurations and additional peripherals for expanded channel capacity.
