Gas Detection System

April 1, 2010

RAE Systems (San Jose, CA) offers the MeshGuard intelligent, connected gas detection system for hazardous gas detection in stationary applications. The MeshGuard family of wireless toxic and flammable gas sensors and monitoring systems is designed for harsh and potentially hazardous locations. MeshGuard wireless systems are available as either system components for custom applications or as a pre-configured Rapid Deployment Kit (RDK) that includes everything required to set up the system and be operational.

System components include the FMC 2000 wireless controller that supports up to 24 sensors. Its built-in wireless modem communicates with each element of the MeshGuard network. It gathers data and monitors all alarms. Housed in a stainless-steel enclosure, it includes five programmable relay outputs, an Ethernet port, RS-485, internal datalog storage on an industry-standard Secure Digital memory card, and built-in audible and visible alarms. For larger deployments, additional FMC 2000s can be clustered. The MeshGuard Router is used to extend the network area coverage to transmit network data signals around obstacles. The wireless MeshGuard monitors are battery powered for fast field deployment. Each monitor can run up to six months on battery power, depending on the specific sensor. Currently available MeshGuard monitors can detect carbon monoxide, hydrogen sulfide, Lower Explosive Limit/Flammability (LEL), and sulphur dioxide.
