Dräger PIR 7000
The PIR 7000 is a SIL 2 approved explosion proof infrared gas detector for the continuous monitoring of flammable gases and vapours. With a 316 stainless steel enclosure and drift free heated measurement optics, it is built for the harshest industrial and offshore applications.
Product features
- Exceptional signal stability
- Based on patented innovations, the Dräger PIR 7000 combines maximum light-efficient optics with a signal-stabilising 4 beam technology. The double-compensating optical system is highly resistant to interference from dust, dirt, fog, or other external effects on the optical surface. Due to its non-imaging nature, the measuring signal of the Dräger PIR 7000 is unaffected by partial beam block, this ensures immunity from false alarm. Two models are available with different measuring wavelengths; this enables the broadest possible range of detectable substances without compromising accuracy.
- Fast response mode
- The sooner a measurable gas concentration is indicated, the faster counter measures can be initiated. The configurable response mode of the Dräger PIR 7000 can be set to "fast" for this purpose. In this mode, each measurable gas concentration is indicated within one second. In conjunction with low alarm thresholds, the gas transmitter can contribute to significantly reducing reaction times in the case of an emergency.
- Maximum reliability – SIL 2 certified!
- The Dräger PIR 7000 was developed and produced in accordance with SIL standards EN 61508 and EN 50402. For the first time ever, the software of a gas detection device was also assessed – the excellent parameters detailed in the SIL 2 certificate issued by the German TÜV confirm the high product quality and reliability of the Dräger PIR 7000: Only two percent of a SIL 2 budget are utilised by the Dräger PIR 7000, leaving great flexibility in the selection of control and other system components. The Dräger PIR 7000 therefore not only meets the SIL 2 requirements but far surpasses them.
- Multiple configuration capabilities
- The optimum default settings of the Dräger PIR 7000 are based on many years of experience. In addition, the PIR 7000 provides the option of user configurable parameters based on customer or application demands. Increased or reduced measuring range, adjustable LEL values, as well as configurable special signals (for fault, beam block warning and maintenance) provides maximum flexibility. A configurable internal gas library with methane, propane and ethylene comes as standard, and ten additional substances can be uploaded.
- Performance features
-
- Two versions (type 334 and type 340) with different measuring wavelengths for different hydrocarbons with different sensitivities
- Double-compensating and non-imaging optics (with 4-beam technology)

- Configurable measuring range in %LEL, %(v/v) and ppm
- Fastest response time of less than 1 second (t0..90 time)
- Analog 4 to 20 mA and digital HART® output signal (including HART multidrop mode)
- Beam block warning signal in the case of contaminated optics for predictive maintenance
- Multiple configuration capabilities of all special signals (in accordance with NAMUR NE 43)
- Specified minimum supply voltage of 13 V DC
- Extended specified temperature range from - 40 °C to + 77 °C / - 40 °C to + 170 °F
- Unrestricted usage in humid atmospheres
- Hermetically sealed 316 stainless steel enclosure
- Long maintenance interval thanks to minimum long-term

List of detectable gases and vapours.
For over 70 years, Dräger has been one of the technology leaders in gas detection.
When there’s danger in the air ... this can quickly pose a high risk to humans, the environment, and all types of property and systems. Recognize the threat before it is too late.
Safety Instrumented Systems are used to reduce the risk for the protection of people, plants, and environment.
Explosion hazards mostly arise from flammable gases and vapours. Instead of avoiding their ignition by explosion protection measures it may be preferable to detect them before they become ignitable.
