RAE Systems has introduced MeshGuard, a rugged single-sensor, battery-powered toxic gas detector integrated with a wireless mesh radio modem for detecting hazardous levels of hydrogen sulfide (H2S) or carbon monoxide (CO). The monitoring units are designed to operate in the full temperature range of -40 degrees to 122 degrees F or -40 degrees to +50 degrees C.
MeshGuard allows for quick installation in hazardous locations, and remote readings for up to 24 monitors are displayed on the FMC 2000 wireless controller. Self-healing and automatic configuration of the network for the best wireless route results in ease of deployment and operation, while ensuring that critical data is delivered to the FMC 2000. Applications for MeshGuard and the FMC 2000 Controller include: oil and gas drilling operations, oil and gas production, plant maintenance, turnarounds, industrial safety, storage tank farms, shipyards and maritime monitoring.
"This new product adds to our suite of solutions for the energy market, and it gives workers a new safety tool that changes the way gas detection is currently deployed in energy exploration and early production," said Bobby Sheikhan, RAE Systems wireless products manager. "We have already seen early deployments of MeshGuard, and the time saved in deploying a wireless gas detection system represents a significant saving in both time and money."
The MeshGuard monitors are intrinsically safe for use in hazardous atmospheres and weatherproof to an IP-65 rating. Each unit can operate up to six months without calibration or battery replacement. The radio range for the units is 300m (1000ft) line of sight, with each unit providing radio relay capability.
The FMC 2000 Controller can manage 24 sensor input channels and provides four programmable single-pole/double-throw (SPDT) relays. The controller includes a backlit display, 14 hours of battery backup and audible and visual alarms all in a stainless-steel package. The controller uses a standard SD-memory card to store alarm and program information.
MeshGuard H2S & CO monitors, and the FMC-2000 controller are available now from select RAE Systems authorized distributors.
