The Drager PEX 3000 detects flammable gases and vapours in concentrations below their Lower Explosion Limit. The Drager PEX 3000 has a DD sensor which provides a very long-term stable measuring signal and responds to gas in only a few seconds.
Benefits:
Six variants of transmitters
You can choose between 2 measuring ranges (0 … 100 or 0 … 10 %LEL) and 2 different junction box sizes. The larger junction box provides optional horizontal or vertical cable entry.
Simple installation
The 3 core screened cable from the control system terminates within the junction box of the Draeger PEX 3000 by means of 3 Ex-approved spring terminals. The sensor connects to 3 different Ex-approved spring terminals.
One-man calibration
Owing to the state-of-the-art design of the Drager PEX 3000 it is possible to open the Ex e junction box in the hazardous area to perform maintenance and calibration. Using the 2 internal push buttons and the internal 7 segment digital display you can perform many different activities including one-man calibration. No additional hardware is required, e.g. a hand held terminal.
Explosion protection
The Drager PEX 3000 is approved according to the EU-Directive 94/9/EC to be operated at ambient temperatures ranging from – 40 up to + 65°C. This applies to both explosive gas atmospheres and explosive dust atmospheres (Zones 1, 2, 21, and 22).
Low gas concentrations
For applications where it is necessary to detect low concentrations then the Drager PEX 3000 type XTR 0010 or XTR 0011 with their special low-drift LC sensor are very suitable. These Draeger Transmitters reliably detect gas leaks of concentrations up to 10 %LEL.
