Dräger Gas Detection Technology
Dräger®Sensors – the heart of our instruments
The heart of every gas detector is its sensor.
The sensor is crucial in determining the quality
of measurements, and therefore it has a
fundamental influence on the safety of the user.
The development and production of sensors
is part of Dräger’s core competence.

What for Detection Technology?
•Flammable and toxic gases and vapors occur in many areas.
•It is important to recognize the danger they pose – and that is the
purpose of gas detection and warning devices.
•Gases and vapors are almost always dangerous. If gases are not
present in the atmospheric composition to which we are accustomed
and which we can breathe, then safe breathing is threatened.
Furthermore, all gases are potentially dangerous in their liquid,
compressed, or normal state – the decisive factor is their concentration.

What for Detection Technology?
There are basically three categories of risk:
– Risk of explosion (ex) caused by flammable gases
– Oxygen (ox)
Risk of suffocation through oxygen deficiency
Risk of increased flammability due to oxygen enrichment
– Risk of poisoning (tox) by toxic gases
