Dräger PEX 3000
The Dräger PEX 3000 is an explosion proof gas detector for the continuous monitoring of flammable gases and vapours in ambient air.
Product features
- Easy to install
- Three wire connection to the transmitter's explosion-protected spring terminals creates a very quick and reliable electrical connection. Available with an extra large body enabling the installation of specialised cable such as SWA is greatly simplified.
- One-man-calibration
- Maintenance of the PEX 3000 is very simple, and can be conducted by opening the housing without declassifying hazardous areas. A simple two button controlled digital display guides the user through procedures without the need for hand held terminals.
- Comprehensive explosion protection
- The Dräger PEX 3000 has been approved in accordance with the ATEX directive for ambient temperatures between -40 and +65 °C Approval is for potentially explosive gas and dust atmospheres (zones 1, 2, 21 and 22). In addition, the PEX 3000 is measurement performance approved in accordance with EN 61779-1, EN 61779-4 and EN 50271 ATEX harmonised standards.
- The detection of low concentrations
- The transmitter PEX 3000 Type XTR 0010 is equipped with a particularly low-drift sensor. This enables reliable detection of low gas concentrations between 0 and 10 % LEL.
- Ideal system solution
- The sensors are based on the catalytic bead (pellistor) detection principle. They contain poison-resistant Dräger pellistors that have been tested and proven over many years. The impact-resistant junction box (EEx e) is constructed from fibre-glass reinforced polyester. Combined with a suitable 4 to 20 mA control unit, the transmitter Dräger PEX 3000 gives ideal operational reliability and system availability.

System Components
The Dräger Catalytic Bead Sensors is designed for the continuous monitoring and detection of combustible gases and vapours – with different versions for different applications or concentrations.
Tried and tested thousands of times and infinitely flexible. The modular Regard control system can be individually adapted to any monitoring task. Suitable for SIL 2 systems, the Regard system is also ATEX approved, and meets EMC directive standards.
The Regard 3900 is a standalone, autonomous control system for up to 16 gas detectors. It is fully configurable and monitors the concentration of toxic gases, oxygen and combustible gases and vapours.
Whether they are mounted to a wall or integrated in the switch cabinet - the flexible small control units Regard 2400 and Regard 2410 reliably monitor the concentration of toxic gases and oxygen as well as combustible gases and vapours.
Robust, reliable and very cost effective. The compact Regard-1 is a complete standalone system for the control of a single gas detector; suitable for monitors of toxic gases, oxygen, combustible gases and vapours.

Literature
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.
