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 30.
Detector positioning
The detector shall be installed with the detector sensor pointing downwards.
For explosive gas detectors only, any tilt of more than 45° from the vertical will
lead to an inaccurate measurement.
