With its stainless steel 316L enclosure and drift free optics, the Dräger PIR 7200 is designed for the harshest industrial and commercial outdoor environments. The unique 4 beam signal stabilizing system makes the sensor resistant to dust or dirt deposits on the optical surfaces. Environmental and ageing effects are largely compensated ensuring long term, drift free operation. The measuring range can be freely adjusted between 0 – 2,000 ppm and 0 – 30% volume enabling a wide variety of applications.
Thanks to its innovative splash guard and waterproof enclosure, the PIR 7200 sensor is ready for extreme conditions such as areas with daily high-pressure wash-downs and extreme temperature and humidity levels. It is available with an integrated Ex e junction box or an aluminum or 316L stainless steel junction box.
PointGard can accommodate additional external alarm devices through its three built-in relays. In addition, a 4–20 mA signal with HART output allows integration into a larger gas detection system.
PointGard’s glass fiber reinforced polyester housing is water and dust resistant with a 4X/IP66 rating. Its compact size allows it to easily fit most applications. Built-in cable glands make it easy to install.
The large, illuminated backlit graphic display shows status information clearly and in a format that’s easy to interpret. The measured gas concentration, selected gas type, and measuring unit are displayed during normal operation. Coloured LEDs (green, yellow, and red) provide additional alarm and status information. Advanced diagnostics log events and gas readings, which can be displayed and a graph created on the display.

The Dräger PIR 7200 sensor is designed to be installed in Zone 1 classified hazardous areas remotely from the PointGard 2720 with a four-conductor shielded cable up to 30 meters long. The cable and Dräger PIR 7200 sensor must be ordered separately from the PointGard 2720.
