4.2 Sensor Transmitter Installation
Mounting location for the gas detectors need to be considered individually, initial points for consideration are:
Ensure all gas detectors are mounted to allow routine calibration and maintenance to be carried out as required.
Ensure the proposed site will not interfere with movement of existing equipment, e.g. cranes, doors etc
Install all cables neatly and securely.
Detectors for gases that are lighter than air should be positioned at, or below, a high level.
Detectors for gases that are heavier than air should be located at below head height.
Avoid location the gas detectors adjacent to potential sources of radio frequency interference, e.g. radio transmitters,
control switchgear, motors etc.
Ensure the detectors are mounted with sufficient space to allow air movement around the sensor section.
