MSA Chemgard (TM) Infrared Gas Monitor for Petrochemical Industry Applications


The Chemgard Infrared Gas Monitor from MSA Instrument Division is a complete, flexible platform ideally suited for gas monitoring in the petrochemical industry. With monitoring ranges as low as 0-10 ppm to as much as 100% by volume for select gases, including LEL monitoring, a durable NEMA 4 enclosure, and advanced photoacoustic infrared sensing technology, the Chemgard Monitor provides accurate, reliable low-level leak detection and
process monitoring.

General hydrocarbons (including methane, pentane, propane and hexane), aromatic hydrocarbons (such as benzene, toluene and xylene), and a variety of fuels (gasoline, diesel andjet fuels) can be detected with the Chemgard Monitor. Applications include tank farm, pipeline and hydrocarbon bed breakthrough monitoring.

The Chemgard Monitor's photoacoustic infrared sensing, a high-performance, low-cost gas detection method, is the technology of choice for low parts-per-million (ppm) or parts-per-billion (ppb) monitoring. It is extremely stable, with virtually no zero drift, and greatly reduces interference effects from background gases and humidity.

Featuring an electrochemical or catalytic bead auxiliary sensor option, the Chemgard Monitor can simultaneously detect either oxygen, carbon monoxide or combustible gas, along with one of over 100 infrared-active compounds. The auxiliary sensor gas concentration can be monitored through the unit display or a 4-20 mA analog output, and the sensor fits conveniently inside the standard Chemgard Monitor enclosure.

The Chemgard Infrared Gas Monitor is available in a NEMA 4 wall mount, a 19" rack-mount, or an explosion-proof enclosure, all with four, front-panel button controls. Each version can monitor from one to eight sample point locations and provides three levels of alarm control.
