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.
Mounting the transmitter
The Sensepoint XCD 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, 40.0-80.0 mm (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.
