(1) Depends on the gas controller
Location of the detector
Depending on the density of the gas to be detected or the application, the detector
shall be positioned at the ground level, or on the ceiling at the same height as the
airflow, or near to the air extraction ducts. Heavy gases may be detected at the
ground level, while light gases will be found at ceiling height. Gas densities are
provided on page 28.
Detector positioning
The detector shall be installed with the detector sensor pointing downwards.
Any tilt of more than 45° from the vertical will lead to an inaccurate measurement.
