CAC harsh-area gas sampling system

Wednesday, 13 March, 2019 | Supplied by: CAC Gas & Instrumentation

The CAC harsh-area gas sampling system is a custom-designed single- or multiple-channel sampling system. It is suitable for monitoring of gas or vapour atmospheres from extreme environments containing temperature, humidity, particulate or pressure challenges.

A powerful air aspirator pulls samples from up to 50 m in distance, which are then filtered and conditioned before being passed across one or multiple detectors. Each detector shares a common calibration and compressed air inlet for aspirated flow. The system is fault-tolerant, removing the need for downtime and maintenance. System integrity is maintained at all times using flow fail monitoring devices, which provide dry contacts that activate if the sample line becomes blocked, damaged, removed or interrupted.

The panel is compatible with a wide variety of specialised sensor technologies supplied by instrument partners to match customer application requirements. Transmitters have 4–20 mA analog signal or digital MODBUS output for direct connection to the site DCS, PLC or control system. The system can provide local alarms and online outputs with a wide range of dry contacts, making the system sophisticated and user-friendly. Integral high-capacity sample filters are included to remove liquids, dust and dirt. Optional battery backup is capable of powering the system during power outages.
