Dräger PIR 7200

When looking for a carbon dioxide monitor you can trust, consider the Dräger PIR 7200. This explosion-proof point gas detection transmitter uses the latest infrared (IR) technology to provide early detection of toxic gas. Designed for a wide variety of industrial environments, the transmitter offers drift-free optics. Due to its robust design and engineering, the PIR 7200 can be operated in harsh industrial environments.

Innovative optical system ensures signal stability

Almost two decades ago, Dräger launched the first fixed infrared gas detector—with more than 100,000 units sold worldwide. The Dräger PIR 7200 builds on that success by incorporating the latest in revolutionary technology.

Based on patented innovations, the Dräger PIR 7200 combines a maximum light collecting design 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 the accumulation of dirt on the optical services, as well as dust, fog or 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 7200 fulfills customer requirements in industrial applications for no false alarms, longer service intervals, and a drift-free signal output.

Early leak detection supports fast response

For optimum safety, it is essential to be informed about a potential CO hazard as early as possible. An early and reliable gas alarm allows you to initiate safety measures on site.

To ensure early warning of a gas leak, the Dräger PIR 7200 offers a configurable response mode which 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 7200 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 7200 offers 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 or increase measuring ranges, or set up special signals (fault, beam block warning, maintenance)—the configurability of the Dräger PIR 7200 enables you to set up every device exactly to your specific needs and preferences.

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

Years of experience in manufacturing gas detectors using infrared technology have enabled Dräger to continuously enhance product quality. With the Dräger PIR 7200, 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 Dräger PIR 7200 not only fulfills but exceeds SIL 2 requirements.
