Drager PEX 3000
The transmitter Drager PEX 3000 is a gas detector for the continuous monitoring
of flammable gases and vapours in the ambient air.
The gas concentration, which is
detected in a range lower than the Lower Explosive Limit (100 %LEL), is converted
to an industry standard 4 to 20 mA signal. Central controllers, like the Drager
REGARD are used to evaluate the signal and activate automatic countermeasures
and alarm devices.
When opening the enclosure, a two digit 7 segment display
with two push buttons is accessible to perform menu guided calibration and
maintenance. With the type XTR 0090, a remote version is also available. Other
enclosure versions with cable glands on the side are available.
Easy to install
Three leads of the measuring cable (max.
length 2.400 m, shielding is recommended)
are pushed into the ex-approved spring
cage clamps. The electrical connection is
One man calibration
Maintenance of the Drager PEX 3000 can
be performed by opening the transmitter -
without declassifying the hazardous area.
By means of two push buttons and a two
digit 7 segment display, the calibration
procedure is menu guided without needing
an additional hand-held terminal.
The sensors are based on the catalytic
bead measuring principle and contain
poison resistant Drager beads, which have
been proven for decades. The small shockresistant
enclosure (EEx e) is made of
conductive, glass fiber reinforced polyester.
Combined with a suitable 4 to 20 mA
controller the Drager PEX 3000
transmitters satisfy the customers'
requirements for maximum safety and
Comprehensive explosion protection
The Drager PEX 3000 is approved
according the ATEX directive for a
temperature range between - 40 and
+ 65 °C. The approval is for potentially
explosive gas- and dust-atmospheres
(zones 1, 2, 21, and 22).
Detection of very low concentrations
The transmitter Drager PEX 3000 type
XTR 0010 is equipped with a special low
drift sensor for reliable detection of gas
concentrations between 0 and 10 %LEL.
