About Dräger
Personal monitoring to plant-wide detection
Whether you need to monitor gas levels while you work or protect a fixed location, Dräger offers portable monitors, transmitters and controllers. You can choose sensors for toxic gases, oxygen levels and flammable gases.
See how sensor choices differ for toxic gases, oxygen and flammable gases.
01
Sensors for specific gases
Electrochemical sensors measure many toxic gases. Each sensor has a measuring range, environmental limits and sensitivity to other gases.
02
Low and high oxygen levels
Oxygen sensors measure the oxygen concentration in the atmosphere. Suitable instruments can warn of oxygen depletion or enrichment.
03
Catalytic or infrared sensing
Catalytic and infrared sensors detect different flammable gases. Infrared sensors do not detect hydrogen; catalytic sensors need oxygen and can be affected by substances that damage the sensing element.
Gas selection begins with the target gas, expected concentration, sensor principle and cross-sensitivities - not the instrument enclosure.
REGARD controllers support defined analog and digital integrations; product literature includes HART and Modbus options on relevant architectures.
Calibration gas, bump-test frequency, sensor replacement and alarm setpoints form part of the lifecycle design.
Frequently asked questions
Quick answers
Can an infrared sensor measure every flammable gas?
No. You need a sensor that responds to the gas you’re monitoring. Hydrogen, for example, needs a different sensing approach. Dräger’s gas-specific data helps you choose the right sensor.
Is a bump test the same as calibration?
No. With a bump test, you check that the instrument responds to test gas. With calibration, you adjust its measurement against a known reference. Follow your instrument’s procedure for each.
Does a SIL-rated transmitter make the whole system SIL 2?
No. You need to assess the complete safety function, including its design, installation and maintenance. A SIL-rated transmitter is only one part of that system.
Should I use a portable or fixed gas detector?
Portable instruments travel with a person or inspection team. Fixed detectors monitor planned positions continuously. Some sites need both; the choice depends on where and when exposure can occur.
What details are needed to replace a Dräger sensor?
Provide the instrument model, sensor part number, target gas and measuring range. Check the required calibration and setup procedure before returning the instrument to service.
Where should a fixed gas detector be installed?
Placement depends on potential leak sources, airflow, gas behaviour and access for testing. Use a site assessment and the detector’s installation instructions rather than choosing height from gas density alone.
