YSI 5200 - Manual (Page 13)

YSI Incorporated 11 5200 Recirculating System Monitor
Note that this is an on-line device that is measuring actual conditions in real time. Composite sampling
for pH, for example, will not match on-line monitoring. Therefore, pH values recorded by the chart
recorder and/or plant control system connected to the 5200 Monitor cannot be averaged to equal the pH of
a composite sample.
3.2.2 Choosing a Monitor Location
The probe measures conditions in the flow stream and transmits a low voltage signal to the 5200 Monitor.
The probe is attached to a cable that is equipped with a “military grade” watertight connection to the
monitor.
Several options are available for mounting the 5200 Monitor. Easy to use, wall mount brackets (006515
Flange Mounting Kit) are provided with the 5200. If rail or panel mounting is desired, the 6509 Rail
Mount Kit and 6510 Panel Mount Kits are available as accessories.
NOTE: The 5200 Monitor is provided with a weatherproof enclosure that will withstand most
environmental conditions with no compromise to system performance. An optional Weather
Shield (YSI #6505) is available for added protection from the elements. When mounting the 5200
outdoors the 6505 Weather Shield should be used.

Locating the monitor close to the sample location has advantages since accuracy checks and calibration
can be more easily facilitated under this arrangement. For example, a recently calibrated, hand-held
dissolved oxygen meter can be placed next to the 5200’s probe and readings can be compared.
Probe cables for the 5200 Monitor are available in 4 (13.1 ft), 10 (32.8 ft) and 20 (65.6 ft) meter lengths.
The probe cable length determines the maximum distance the monitor can be mounted from the sample
being measured.
Location of the 5200 Monitor should be elevated and in a dry place above the potential flood level. The
unit should be easily accessible for an operator or technician.
Although the monitor is suitable for outdoor use, it should be located in an area where temperature
extremes, vibrations, electromagnetic and radio frequency interference are minimal. Select an installation
location that is at least two (2) feet from any high voltage conduit. Avoid mounting on severely vibrating
