Dräger PEX 3000
Fixed Gas Detector
EXPLOSION PROTECTION
You can choose between two measuring
ranges (0 ... 100 or 0 ... 10 %LEL) and two different junction box sizes. The larger junction
box provides optional horizontal or vertical
cable entry. Where the application asks for
the sensor to be mounted remote from the
junction box then it is possible to use the
remote cable assembly combined with the
sensing head of type Polytron SE Ex.
The Dräger 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).
SIMPLE INSTALLATION
The three core screened cable from the
control system terminates within the
junction box of the Dräger PEX 3000 by
means of three Ex-approved spring
terminals. The sensor connects to three
different Ex-approved spring terminals.
Ex-approved spring terminals are not selfloosening and are inherently more reliable
then standard screw terminals, therefore
self-loosening is no longer an issue!
ONE-MAN CALIBRATION
Owing to the state-of-the-art design of the
Dräger PEX 3000 it is possible to open the
Ex e junction box in the hazardous area to
perform maintenance and calibration. Using
the two internal push buttons and the internal seven segment digital display you can
perform many different activities including
one-man calibration. No additional hardware is required, e.g. a hand held terminal.
LOW GAS CONCENTRATIONS
For applications where it is necessary to
detect low concentrations then the transmitters Dräger PEX 3000 type XTR 0010
or XTR 0011 with their special low-drift
LC sensor are very suitable. These
transmitters reliably detect gas leaks of
concentrations up to 10 %LEL .

The transmitter Dräger PEX 3000 detects flammable gases
and vapors in concentrations below their Lower Explosion
Limit. Its DD-sensor provides a very long-term stable
measuring signal and responds to gas in only a few seconds.
NEWLY DEVELOPED: DD SENSOR
The new DD sensor is based on the
well-known catalytic bead technology from
Dräger and is designed and manufactured
by Dräger for long term stability and
resistance against sensor poisons.
Furthermore, the new DD sensor uses an
innovative non-sintered disc gas inlet
therefore the reaction time towards the
target gas in now only a few seconds. This
fast speed of detection allows for countermeasures to be initiated earlier, therefore
guarding against the formation of an
explosive atmosphere.
