5.1 Mounting and location
Gas detectors should be mounted where a potential hazard of gas is most likely to be
present. The following points should be noted when locating gas sensors.
• When locating detectors consider the possible damage caused by natural events e.g.
rain or flooding.
• Consider ease of access to the gas detector for functional testing and servicing.
• Consider how escaping gas may behave due to natural or forced air currents.
Note: The placement of gas detectors should be determined following the advice of
experts having specialist knowledge of gas dispersion, experts having knowledge of
the process plant system and equipment involved, safety and engineering personnel.
The agreement reached on the location of detectors should be recorded.
5.2 Mounting the transmitter
The Sensepoint XCD RFD transmitter has an integral mounting plate consisting of four
mounting holes on the transmitter body. The transmitter may be fixed directly to a surface
mounting, or to a horizontal or vertical pipe/structure, 40.0-80.0mm (1.6 to 3.1 inches) in
diameter/cross section. The Pipe Mounting Bracket accessory (optional accessory) may
be used for this purpose.
Caution: The location of gas detectors should be made in accordance with any relevant
local and national legislation, standards or codes of practice. Always replace sensors
with a sensor of the same type.
