Dräger PIR® 7000

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.

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.

Choose a target gas with the embedded gas library

Dräger PIR 7000 comes standard with 3 gases (methane, propane, ethylene) and a maximum capacity of 10 embedded gases in its memory. Update the embedded gas library from a list of over 80 available gases using Dräger Polysoft® Premium software for a high degree of application flexibility.

Switch between the embedded library target gases without having to recalibrate the sensor. Any gas in the library can automatically be cross-calibrated with commercially available calibration gases such as methane or propane without needing complicated correction factors. The measuring range can be freely adjusted between 0 – 350 ppm and 0 – 100 % LEL enabling a wide variety of applications.

The available Dräger PRC PC software allows for automatic on the fly changing of target gas curves during operation for process applications such as solvent drying ovens.

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.

Early detection enables fast response

For optimal safety, it is essential to be informed about a potential hazard as early as possible. A reliable gas monitor that detects leakages at the earliest stage allows you to initiate safety measures on site.

To support fast response, the Dräger PIR 7000 offers a configurable response mode that lets you choose between “normal” or “high speed” response, subject to the application. By using the “high speed” option, and combining it with the lowest feasible alarm threshold, the Dräger PIR 7000 shortens the reaction time in case of an alarm. Leakages can be detected at the earliest stage of their existence.

Multiple configuration capabilities

The Dräger PIR 7000 has a maximum number of default settings, but remains fully flexible to meet your needs on an application-by-application basis—whether you want to reduce measuring ranges, configure special signals (fault, beam block warning, maintenance), or adjust LEL values that are different across regions, all coupled with the configurable gas library (for other substances to be monitored). All these features of the Dräger PIR 7000 enable you to set up every device exactly to your specific needs and preferences.

Standards-based design ensures high safety and reliability—SIL 2 certified

Over two decades of experience with infrared technology has enabled Dräger to continuously enhance product quality. With the Dräger PIR 7000, the entire product—hardware and software—has been developed according to the Functional Safety standard EN 61508.

The International Electrotechnical Commission's (IEC) standard IEC 61508 defines Safety Integrity Level (SIL) using requirements grouped into two broad categories: hardware safety integrity and systematic safety integrity. A device or system must meet the requirements for both categories to achieve a given SIL.

The Drager PIR 7000 not only fulfills but exceeds SIL 2 requirements.

The productivity of a continuous flow dryer depends on the setting of the installed gas transmitters. The more precise they are calibrated to the used solvent mixture, the safer is the plant in operation. Up to now in particular, in case of frequently changing compositions, this accuracy had to be acquired with long downtimes of the continuous flow dryer.
