About this Sensor
The CDP chlorine dioxide probe is a membrane covered amperometric
dual electrode sensor. It is used to determine chlorine dioxide concentra-
tions in water with or without surfactants present. This sensor has been
developed for use in bottle washing systems (water containing surfactants,
sudden temperature changes). The sensor emits a standard 4 - 20 mA
signal via a two wire interface that is largely unaffected by water flow. Power
is also supplied to the sensor via the two-wire interface.

Safety
Correct use of equipment
The sensor may be used only to determine and regulate chlorine dioxide
concentrations (ClO
2
).
All other applications and modification of this equipment are forbidden.
The sensor is not a safety component!
CAUTION
•
The sensor will operate correctly only if used in a
purpose-designed ProMinent probe housing assembly
(see Assembly).
•
The sensor can be operated only with a DULCOMETER
®
D1C measurement and control device with automatic
temperature correction. (Identity code:
D1CAxxD12x1xxxxxx or D1CAxxD13x1xxxxxx).
•
There must be free discharge from the probe housing
assembly.
•
The supply voltage to the measuring device and the
sensor must not be interrupted. After long intervals
without power (more than 2 h) the probe should be given
a further run-in period and recalibrated (see 7.1 “Run-in
period” and 7.2 “ Calibration”).
IMPORTANT
•
The probe may be assembled, installed, serviced and
operated only by appropriately trained and authorised
personnel.
•
Check the sensor regularly for dirt, algae growth and air
bubbles. (see 8 “Troubleshooting”).
•
Observe valid national directives for the maintenance,
servicing and calibration intervals.
