Technical data

The sensor is the heart of any gas detection instrument. Dräger is one of the few
manufacturers of gas detection instruments who also make their own sensors and
we have more experience with this technology than anyone else. Over many years,
Dräger-Sensors
®
have proven themselves, even under the most difficult conditions.
Our latest generation of sensors, the Extra Stability (XS), provide outstanding
performance in a wide range of industrial applications.
DRÄGER-SENSOR

XS-2
Our XS-2 Sensors offer the same advanced
technology of the other Dräger-Sensors
®
in a value priced package. Available for CO,
H
2
S and O
2
, these sensors come with a
standard 2-year warranty. Even this series
of Dräger-Sensors
®
offers superior perfor-
mance and stability over other sensor
brands.

XXS FEATURES
- The longest warranties offered by any
manufacturer
- Fast and accurate response to changing
gas concentrations
- Extra stability sensors that drift less and
require less frequent calibration
- Superior operating temperature range
(-40 to +105 °F / -40 to +40 °C) and
stability due to an internal thermal
compensating device
- A wide operating pressure range
(20.7 to 38.4 in Hg /700 to 1300 mbar)
due to a unique mechanical design of
the sensor
- The ability to withstand and recover
from high concentration exposures
- Calibration intervals of 6-12 months

XXS combines “New
Sensor Technology” from the Dräger
Pac 7000 with “Dräger Sensor
Technology” from the Dräger X-am 5000

XS-R
The XS-R sensors offer the longest
warranties and require the least mainte-
nance of any sensor in the industry. The
Dräger-Sensors
®
XS-R for CO, H
2
S and O
2
are covered by an unequalled 5-Year
Warranty! Yes, even our O
2
sensor which
continuously detects oxygen for a period of
5 years! This is far better than what other
manufacturers can offer. Calibration is only
required on a yearly basis which greatly
reduces down time and maintenance
costs. The XS-R series offers the best cost
of ownership through their unsurpassed
stability and longevity.
DRÄGER-SENSOR

XS
There are 34 different XS sensors currently
available that will measure over 50 different
toxic gases and vapors. This is possible
through our patented three-electrode sensor
technology and internal filter media that
maximizes response to the gas of concern
while greatly reducing responses to other
gases that may be present. The superior
stability and accuracy of Dräger-Sensors
®
is
especially evident on the reactive gas and
exotic gas sensors where longer lives and
less frequent calibration is required. The
large selection of Dräger-Sensors
®
allows
you to meet a wider range of gas detection
applications with your Pac 7000, X-am 2000,
X-am 5000, X-am 5500 or X-am 7000 monitors.

XS are provided with a long
3-year warranty.
