Real-Time Environmental Monitoring
Environmental corrosion monitoring provides the short-term data needed to detect and limit the number of corrosion-causing occurrences. The traditional method of environmental corrosion monitoring requires the use of Corrosion Classification Coupons (CCCs). While this method is effective at characterizing an environment's corrosive potential, the time required for field exposure and analysis may generate results long after process and motor control systems have been damaged by corrosive gases. To protect these capital investments, Purafil created the industry's first real-time electronic corrosion monitor.

OnGuard 3000 Atmospheric Corrosion Monitor
Purafil's OnGuard 3000 Atmospheric Corrosion Monitor is the first electronic instrument which provides real-time readings of an environment's corrosive reactivity level. The OnGuard also provides real-time temperature and relative humidity readings which affect the rate of corrosion. By using OnGuard, users may take preventive action before corrosion damage leads to costly repairs and production downtime. And because the OnGuard 3000 Monitor correlates with standards set by the Instrumentation Society of America (ISA) for classification of industrial environments, the OnGuard may be used to ensure manufacturers' warranties on electrical equipment.

 

OnGuard Continuous Corrosion Transmitter
The OnGuard Continuous Corrosion Transmitter (CCT) measures in real-time the amount of corrosion forming on copper and silver surfaces, and transmits this information to the control system via a 4-20 mA output signal. Cumulative or incremental data can be logged, allowing for the detection and measurement of isolated, corrosion-causing events. All OnGuard CCT measurements can be related to Instrument Society of America-Standard S71.04-1985, which defines an environment as either G1, G2, G3, or GX, based on the corrosion severity level and potential effects on equipment reliability.
