CS511 Dissolved Oxygen Sensor
1. Introduction
The CS511 is a rugged, low-maintenance sensor that is manufactured by
Sensorex. It consists of a self-polarizing galvanic cell that generates a millivolt
signal proportional to the amount of oxygen present in the measured medium
(typically water).
This manual provides information only for CRBasic dataloggers.
For retired Edlog datalogger support, see a retired manual at
www.campbellsci.com\old-manuals
. Also refer to a retired manual
if the CS511 was purchased before June 2008 and for information
on using the retired PT4-L Agitator.
2. Precautions
•
section at the front of this
manual.
•
The CS511 is a precision instrument. Please handle it with care.
•
Because the CS511 is shipped dry, electrolyte needs to be added before
(p. 7)
).
•
Letting the CS511 dry in the field shortens the life of the membrane and
sensor.
•
The sensor should be stored dry and empty. Therefore, empty the
electrolyte, rinse the sensor, and remove the membrane.
•
Replace the membrane and recalibrate the sensor before redeploying the
CS511 after it has been stored out of water or dried up in the field.
•
While cleaning, do not touch the center electrode (Section
(p. 11)
).
3. Initial Inspection
•
Upon receipt of the CS511, inspect the packaging and contents for
damage. File damage claims with the shipping company.
•
Immediately check package contents against the shipping documentation
(p. 2)
). Contact Campbell Scientific about any
discrepancies.
•
The model number and cable length are printed on a label at the
connection end of the cable. Check this information against the shipping
documents to ensure the expected product and cable length were received.
