Part 2 – Analyzer Mounting
2.1 General
All Q46 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 PAA 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.
