Intended Use

Intended Use

The Dräger PIR 3000 infrared gas transmitter is a device used for stationary,

continuous monitoring of the concentration of carburetted, combustible gases and

vapours in the ambient air.

The gas transmitter is preconfigured for the gases methane, propane and ethylene.

The operating range respectively covers 0 to 100 %LEL (

ower

xplosion

imit).

An analogue, 4 to 20 mA output signal is used as measuring value output.

The Dräger PIR 3000 infrared gas transmitter is designed for use in rough ambient

conditions and is suited for installation in hazardous areas of zones 1, 2, 21 and 22

according to the device categories 2G, 3G, 2D, 3D or Class I & II, Div. 1 for

hazardous areas. For further information, please observe the installation

instructions.

In connection with a central device (e.g. Dräger REGARD channel card

4...20 mA):

— warning before explosive concentration level is reached

— automatic initiation of countermeasures which avert the explosion hazard (e.g.

switching on a ventilation)

— device error warning
