Sensepoint XCD RTD Technical Manual
5.1 Mounting and location
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
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.
The Honeywell Analytics Gas Book may be referred to for further useful information
regarding gas detector mounting and location. Please contact your local sales/service
agent for a copy.
5.2 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, 40.0-80.0mm (1.6 to 3.1 inches) in
diameter/cross section. The Pipe Mounting Bracket accessory (optional accessory) may
be used for this purpose.
