Watchdog Scout

Web-based Remote Monitoring System with Interruption Capabilities


The Watchdog Scout combines the installation simplicity of our VIP system with the advanced, web-based interruption capabilities of the groundbreaking Watchdog Mesh system. The Scout is designed to withstand all the challenges encountered in CP rectifier monitoring applications. The compact sized, lockable NEMA4x enclosure provides a secure, protective environment for the state of the art electronics. Advanced, self-testing circuitry automatically verifies the channel calibration to a known, stable voltage with every reading. This assures the most accurate reading available, every time!

The Scout has been rigorously tested to withstand voltage surges up to 7500V at 3500A using conducted voltage testing per IEC 61000-4-5 specifications. This test method most closely correlates with the lightning and input power surges encountered by remote monitor equipment in the field.

The powerful Pipeline Watchdog web interface provides instant visibility to the status of your field assets, and simplifies multiple rectifier GPS-synchronized interruption, group polling, and automatic compliance report generation.
