INSTALLATION
2.3.2 Transmitter Mounting - Direct Pipeline Connection
The transmitter may be directly mounted into a pipe or duct as shown in Figure 6.
Caution: Do not mount the transmitter too close to the bottom
of a bend where any condensate in the pipeline might collect
and saturate the probe.
The pipe or duct will require a thread to match the transmitter body thread. Fixing
dimensions are shown in Figure 6. For circular pipework, to ensure the integrity of a
gas tight seal, a mounting fl ange will be required on the pipework in order to provide a
fl at surface to seal against.
The following procedure must be carried out by competent
personnel.
WARNING: Under no circumstances should the fi lter disc be
handled with the fi ngers.
1. G ½” ONLY - Ensure that the bonded seal (2) is over the threaded part
of the transmitter body.
2. Screw the transmitter (3) into the pipe (1). Tighten enough to obtain
a gas tight seal. NOTE: Do not overtighten or the thread on the
pipework may be stripped.
