The Watchdog P2S-AC makes it possible to obtain critical CP field data, such as AC corrosion current density, induced AC voltage, critical bond current, and IR-drop free (instant-OFF) potential, that were previously difficult or costly to measure. Installed at a CP test point with a dual coupon test station or at a critical bond, the P2S-AC delivers accurate and reliable data to the Pipeline Watchdog website via GSM or

geostationary satellite telemetry.

The P2S-AC transmits regular readings at a programmable interval, with alarms for out-of-normal conditions. Knowing native potential, ON potential, and OFF potential gives the CP professional powerful data to analyze the effectiveness of the cathodic protection system.

The P2S-AC is the perfect tool to better understand AC corrosion issues. Use it to log data during field studies, then permanently monitor the effectiveness of your AC mitigation system.

The unit can function as a CP data logger, taking and storing measurements as often as every 15 seconds. Use it to perform field studies on variable effects on your CP system such as: changing electric transmission line loads, electric rail effects, crossing pipeline interference, and variable soil conditions. The 2 GB SDRAM card can hold several months of data, which can be transmitted to the user via the GSM/ GPRS cellular link or retrieved manually.
