Regulations and conditions of use 

The sensor in the transmitter should always be in contact with the ambient air. 

Therefore: 

-  Do not cover the detector. 

-  Do not paint the detector. 

- Avoid 

dust. 

 

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. 

Detector positioning   

The detectors shall preferably be positioned in an accessible place to facilitate the 
operations of inspection and maintenance as well as the absolute safety of the 
operators. The detectors must not be obstructed by anything that will prevent 
them from measuring the ambient environment to be checked. 

 

The detector shall be installed with the cable gland pointing downwards

.  

For explosive gas detectors only, any tilt of more than 45° from the vertical will 
lead to an inaccurate measurement.
