大气抽样系统

Designed for use in Zone 1 or Zone 2 hazardous areas, the air aspirated systemuses a compressed air driven vacuum generator to draw a gas sample from asingle point. Explosion-proof gas detectors are fitted to monitor for flammablegases, toxic gases or oxygen. Each detector provides a 4-20mA output. Anintrinsically safe flow-fail device warns if the sample flow is lost due to supply air failure or sample line blockage. The system is ideally suited for monitoring flammable gas leaks within turbine enclosures, solvent detection in painting or printing processes or monitoring oxygen levels in industrial processes.
