Elecsys Watchdog TrackerCR

Install the Watchdog Tracker CR to automatically keep track of AC interference corrosion risk. That way, you can stay ahead of problems. The Watchdog Tracker CR measures corrosion rate with a custom-built probe, along with pipeline potentials and current densities, all at a regular rate. These readings get archived in the Watchdog Tracker CR’s built-in data logger, and are wirelessly forwarded to Elecsys Connect where they can be checked from any web-enabled device.

Description

Description

The Tracker CR is the latest in our popular Tracker family of test station monitoring products. The Tracker CR is designed to be the all-in-one solution for data acquisition and corrosion risk assessment in high AC interference areas. The Tracker CR measures, records, and transmits pipeline potentials, current densities, and corrosion rate values for compliance with the NACE SP21424 standard. Typical measurement intervals for standard compliance are taking voltage measurements and current density measurements hourly in order to account for the expected fluctuations occurring in AC interference. Like all of the Watchdog CP monitoring systems, the Tracker is designed and manufactured in the USA at our state of the art manufacturing facility in Olathe, Kansas. Take control and avoid the catastrophic structural damage that nearby electrical fields can cause. Maintain high integrity of your pipeline management program with the new Watchdog Tracker CR.

Applications

Corrosion Rate measurements using a custom-designed 1cmÇ ER probe
AC & DC current density measurements
On/Off potentials at coupon test stations
Turnkey system including monitor and ground probe
Cost-effective communication
Built-in data logger
Elecsys Connect web-interface

Benefits

Corrosion rate monitoring

AC interference can do serious corrosion damage to pipelines. The Watchdog Tracker CR monitors that corrosion rate, alerts you when things change, and keeps you in control. It’s the best way to know how well your corrosion mitigation system is working. That way, you stay ahead of AC interference problems before they ever happen.

Remote monitoring

Stay on top of pipeline voltage and density monitoring wherever you go. The Watchdog Tracker CR sends alarm notifications automatically, which you can see from any web-enabled device. You’ll have corrosion risk under control before it ever becomes an issue and you can do it without traveling to a test station.

User-friendly interface

Access Watchdog Tracker CR data and notifications with Elecsys Connect on the web or on-the-go; our robust interface with customizable alerts is designed specifically around your needs. It makes corrosion risk monitoring easier, clearer, and much more intuitive.

Built-in data logging

The Watchdog Tracker CR features a built-in data-logging system, which you can use for long-term analysis and better overall management.
