Part 2 – Analyzer Mounting
2.1
General
All Q45 Series instruments offer maximum mounting flexibility. A bracket is
included with each unit that allows mounting to walls or pipes. In all cases,
choose a location that is readily accessible for calibrations. Also consider that it
may be necessary to utilize a location where solutions can be used during the
calibration process. To take full advantage of the high contrast display, mount
the instrument in a location where the display can be viewed from various angles
and long distances.
Locate the instrument in close proximity to the point of sensor installation - this
will allow easy access during calibration. The sensor-to-instrument distance
should not exceed 100 feet. To maximize signal-to-noise ratio however, work
with the shortest sensor cable possible. The standard cable length of the oxygen
sensor is 25 feet.
Due to the flexibility of the instrument design, some of the mounting features
change based on the configuration that was ordered. For example, the 2-wire
transmitter version is different for the 115/230 VAC controller because the rear of
the enclosure is much deeper when the AC powered unit is used. In addition, the
AC powered unit has an integrated panel mount flange requiring a single cutout
for flush mounting. In the 2-wire transmitter configuration, just the front of the
enclosure can be mounted, but the cutout also requires accurate location of 4
mounting holes. Refer to Figures 2-1 and 2-2 for detailed dimensions of each
type of system.
