Dräger PIR 7000 fixed gas detection

Constant monitoring of flammable gases and vapors is essential for a safe workplace. The Dräger PIR® 7000 is an explosion-proof point gas detection transmitter that uses infrared (IR) technology to continuously monitor flammable gases and vapors. With its stainless steel SS 316L enclosure and drift-free optics, this detector is built for the harshest industrial environments,
including offshore installations.

Benefits

Accurately detects a wide range of flammable substances

Two models of the Dräger PIR 7000 are available—type 334 and type 340. Each model works with a different measuring wavelength, thus detecting the broadest possible range of flammable substances with superior accuracy.

Advanced signal stability

Following the success of the most stable point infrared gas detector worldwide—the Dräger Polytron IR— Dräger has introduced the PIR 7000, which encompasses the latest in revolutionary technology.

Based on patented innovations, the Dräger PIR 7000 combines a maximum light collecting construction with a 4-beam signal stabilizing system. The total optical system uses no light beam split, simply a set of various reflectors. This double-compensating optical system is very resistant to accumulation of dirt on the optical surface, as well as known influences such as dust, fog and insects, which are frequently found in the measuring cuvette. Due to its non-imaging construction, the measuring signal is not affected by a partial beam block.

This innovative optical system ensures that the Dräger PIR 7000 fulfills the customer requirements of no false alarms, longer service intervals, and a drift-free signal output.
