<strong><strong>RAE</strong>Guard</strong> <strong>LEL</strong>Fixed Combustible Gas Monitor, 4-20 mA transmitterThe <strong><strong>RAE</strong>Guard</strong> <strong>LEL</strong> is apermanently mounted (fixed)catalytic bead combustible gastransmitter that operates from 9to 36 VDC power source andprovides a 4-20mA analog outputin the range of 0-100%<strong>LEL</strong>combustible gas. Themicroprocessor based circuit ishoused in an explosion-proofenclosure, the <strong><strong>RAE</strong>Guard</strong> <strong>LEL</strong>is equipped with a local digitaldisplay of the gas concentrationand function keys for performingcalibration. The <strong><strong>RAE</strong>Guard</strong> <strong>LEL</strong>is operated with a standard4-20mA controller or as astand-alone sensor module.Key Features• Highly poison-resistantcatalytic bead combustiblegas <strong>LEL</strong> sensor• 4-20mA analog output of0-100%<strong>LEL</strong> combustible gasincluding methane,acetylene, propane or othercombustible gases• Explosion-proof enclosurefor hazardous environmentapplication• Magnetic key interfaceeliminates need to openexplosion-proof housingwhen making calibration orother minor adjustments• Operation at 9 to 36 VDC• Dry contact output (
