Dräger PIR 7000

Fast response Equally important is being informed about a potential hazard as early as possible. An early and reliable gas alarmallows for safety measures to be initiatedon site. To support this, the Dräger PIR 7000offers a configurable response modewhich allows the end user to choose between “normal” or “high speed”response subject to the application. Using the “high speed” option, andcombining it with the lowest feasible alarm threshold, the Dräger PIR 7000shortens the reaction time in case of analarm. Leakages can be detected at theearliest stage of their existence.

The Dräger PIR 7000 is an explosion proof point infrared gasdetector for continuous monitoring of flammable gases and vapours. With its stainless steel SS 316L enclosure and drift- free optics this detector is built for the harshest industrial environments, e.g. offshore installations.

Two models of the Dräger PIR 7000 areavailable – type 334 and type 340. Eachmodel works with a different measuringwavelength, thus giving the broadestpossible range of detectable substanceswith superior accuracy. Advanced signal stability Following the success of the most stablepoint infrared gas detector worldwide –the Dräger Polytron IR – Dräger now introduce the Dräger PIR 7000 which encompasses the latest in revolutionary technology. Based on patented innovations, theDräger PIR 7000 combines a maximumlight collecting construction with a 4-beam signal stabilising system. The total optical system uses no light beamsplit, simply a set of various reflectors.This double-compensating optical system is very resistant towards known influences such as dust, fog or insectsfrequently found in the measuring cuvetteor by dirt accumulation on the optical surfaces. Due to its non-imaging construction, the measuring signal is notaffected by a partial beam block. This innovative optical system ensuresthat the Dräger PIR 7000 fulfils thecustomer requirements of “no false alarms”, longer service intervals and adrift-free signal output.
