Bently Nevada 3500/63 Gas monitor

Description

The 3500/63 Hazardous Gas Monitor is a six-channelmonitor that is used as a safety-system element byproviding levels of alarms based on the concentration ofcombustible gases. An alarm issued by this monitorindicates that the gas concentration is sufficient to causepersonal safety concerns because of explosion orasphyxiation. It is designed for use with heated catalyticbead gas sensors (Hydrogen and Methane) and indicateshazardous gas concentration as a percentage of the lowerexplosive level (LEL). The monitors can be utilized ineither a simplex or redundant (TMR) 3500 Rackconfiguration..The Hazardous Gas Monitor application is particularlysuited for enclosed or confined spaces where combustiblegases are used as fuels or are being handled, pumped orcompressed. If a leak occurs, the gases may accumulateand reach a potentially explosive concentration. Detectionand alarming on gas concentrations is critical for the
protection of personnel in the area and for the protection ofthe equipment. Housings around natural gas firedindustrial gas turbines, hydrogen pipeline compressors, orcompressor doghouses are all examples of confinedspaces where combustible gases could accumulate.When used in a Triple Modular Redundant (TMR)configuration, Hazardous Gas Monitors must be installedadjacent to each other in groups of three. When used inthis configuration, two types of voting are employed toinsure accurate operation and to avoid single- pointfailures.
