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 is an ideal 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 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 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 GSMGPRS cellular link or retrieved manually.

Farwest UltraProbe Series impressed current probe anodes are an effective solution when there is a need to protect the internal surfaces of a structure, such as a condenser water box, process tank, pressure vessel, intake discharge piping, or similar. Available in a wide variety of sizes, materials and configurations, these probe anodes allow through-wall installation of the anode from the exterior of the structure. Anode Materials The anode element is available in a number of material choices including: Platinized niobium* Platinized titanium* Mixed metal oxide (MMO)** * Platinum thickness can vary from 50 to 300 microinches. Physical Considerations Depending on the probe anode application, diameter of the anode, flow rates and other considerations, probe anodes may or may not require the use of a non-metallic support shield. This shield is designed to provide structural support to the anode rod and to provide current shielding properties. For instance, a 0.750” diameter anode may not need a support shield, whereas a 0.375” diameter anode may need additional mechanical support.

The Elecsys VIP-XT is the answer to the corrosion professional’s need for a simple, reliable and low-cost CP transformerrectifier remote monitor. The unit comes from the factory configured to measure transformer rectifier output volts, amps, pipe-to-soil potential, and AC mains detection. The unit is highly flexible, with four configurable analog inputs, one digital input, and the AC detection probe, allowing it to handle a wide variety of remote monitoring needs for pipelines, plants and refineries, oil and gas well sites, and distribution utilities. Using field-proven lightning surge-resistant circuitry, the VIPxt system is the best choice for cost-effective transformerrectifier monitoring on oil, gas and water pipelines, offshore platforms, well casings and piers.

• Size6.5” (155 mm) X 8.5” (215 mm) X 4” (102 mm)

The Watchdog VIPx is specifically designed for most rectifier monitoring applications. Features include pre-configured, dedicated analog measurement channels for volts, current, and pipe to soil. Unit is equipped with an AC Probe to detect and monitor the rectifier input power. An additional dry contact digital channel can be used for momentary alarm monitoring (door alarm for intrusion detection for example), or for status monitoring (valve position, etc.).
