March 18, 2010 - Elecsys released the WatchdogCP P2S-AC Cathodic Protection Test Station Monitoring System. The product is designed to obtain IR-free pipe-to-soil potential measurements along with AC and DC corrosion current densities by integrating with either traditional buried reference cells, single, or dual coupon cathodic protection (CP) test stations. The unit also functions as a multi-channel critical bond monitor. Data is continually logged and can either be accessed through the existing Pipeline Watchdog website or retrieved from a 2GB SD memory card within the unit.By setting value ranges and sample rate intervals through the web application, clients are able to improve pipeline integrity by analyzing trends in on/off potentials, AC values and depolarization test data.
In addition, the website allows immediate access to instant-off potential measurements for complete groups of test stations and provides web-based remote control of measurement ranges, group configurations, and alarm notification settings.Up to 10 separate remote units within a 3 mile radius can be monitored with just a single P2S-AC unit equipped with a GSM cellular or satellite modem, thereby reducing the monthly messaging cost per test station and extending test point coverage.
