2.1 Areas of application
These membrane-covered amperometric sensors are used to measure the concentration of hydrogen
peroxide or peracetic acid in aqueous solutions.
Typical areas of application are galvanizing plants, the pharmaceutical field, the food and beverage in-
dustry, dairies and the chemical industry.
The sensors are partially insensitive to chemicals and surfactants, and can be used in media with almost
all qualities of water.
NOTE!
Solid materials in the media clog up the membrane and prevent the sensors from working correctly.
NOTE!
Calcium oxide can block the membrane.
NOTE!
The sensors are not suitable for detecting the absence of hydrogen peroxide or peracetic acid.
2.2 Design
The sensors have a membrane-covered, amperometric two-electrode measuring system.
The working electrodes (cathodes) are made of gold (Au). The anodes, which perform the role of a com-
bined reference and counter electrode, are made of silver (Ag) and have a silver halide (AgHal) coating.
For the measuring methods used here, hydrogen peroxide or peracetic acid diffuses through the mem-
brane from the measurement medium and, combined with the electrolytes, triggers an electrical signal
at the working electrode. This signal is proportional to the concentration of chlorine dioxide or ozone and
is amplified by the electronics. The measurement signal is mainly independent of the temperature of the
media thanks to integrated temperature compensation.
2.3 Output signal
As the measurement signal of the amperometric sensors is temperature-dependent, an automatic tem-
perature compensation is carried out by an integrated NTC resistor. The recommended temperature
range is 01 to +45 °C.
In the analog versions, the integrated sensor electronics provide a current signal of 4 to 20 mA, and in
the digital versions, they provide a Modbus RTU interface signal.
Calibration is carried out in a downstream device (indicator, controller, recorder, PLC, etc.).
The sensors can be connected directly to any suitable indicators and controllers. They provide the volt-
age required for supplying the sensors and allow for easy calibration of the measuring systems.
1Prerequisite: no ice crystals in the measuring water.

2.6 Important information for use
2.6.1 Notes for all types
NOTICE
Unsuitable measurement media may produce incorrect measurement results.
Using the sensors to measure contaminated media (dirt particles, foreign objects, fibers, etc.) may lead
to incorrect measurement results.
In order to ensure error-free measurements, the measurement media must be visibly clean. A pre-
filter must also be used, as required.
NOTICE
An unsuitable measuring environment may produce incorrect measurement results.
Using the sensors without the use of suitable flow fittings will lead to incorrect measurement results.
In order to ensure error-free measurements, the sensors must be installed in suitable flow fittings,
see chapter 4.2 "Combination fitting (type 202811/10)", page 19 or chapter 4.3 "Flow fitting for mem-
brane-covered sensors (type 202811/30)", page 22.
NOTICE
Incorrect handling may cause damage to the membrane caps.
Screwing an unfilled membrane cap fully onto the sensor before startup may cause mechanical damage
to the membrane. In addition, screwing on a filled membrane cap without placing the sensor into the
measurement media can cause salt or gel residues to be deposited.
Screwing on the membrane cap without then starting up the sensor should be avoided.
NOTICE
The membranes may be damaged by high pressure.
Operating the sensors with increased pressure may cause the membranes to rip.
The sensors should be operated under as little pressure as possible, with the measurement media
able to flow freely. If this is not possible, the sensors can be operated under a constant pressure of
up to 1 bar (relative pressure) or 2 bar (absolute pressure). Fluctuations in pressure must be avoid-
ed.
2.6.2 Types with valve opening in the membrane cap (202636/55-45, -60, -70, -75 and
202636/60-60, -70, -80)
The measurement water must not contain any surfactants (contained in some cleaning agents and dis-
infectants). Surfactants may infiltrate the valve cover of the membrane cap. It can therefore no longer be
guaranteed that the sensors will work correctly.
The sensors for hydrogen peroxide and peracetic acid with a digital interface and internal pressure com-
pensation system (types 202636/75 and 202636/80) provide an alternative for measurement solutions
containing surfactants.

NOTICE
Irritating substances may produce incorrect measurement results.
Using the sensors to measure media containing surfactants may lead to incorrect measurement results.
In order to ensure error-free measurements, the measurement media must not contain surfactants
(surface-active substances e.g. from detergents, cleaning agents or disinfectants).
NOTICE
Harmful substances may lead to incorrect measurement results and cause damage to the mem-
brane caps.
Using the sensors to measure media containing hydrophobic substances may lead to incorrect measure-
ment results. Hydrophobic substances can damage the membrane caps.
In order to ensure error-free measurements, the measurement media must not contain hydrophobic
substances (e.g. oil or grease).

4.1 Important information
NOTICE
An unsuitable measuring environment may produce incorrect measurement results.
Using the sensors without the use of suitable flow fittings will lead to incorrect measurement results.
In order to ensure error-free measurements, the sensors must be installed in suitable flow fittings,
see chapter 4.2 "Combination fitting (type 202811/10)", page 19 or chapter 4.3 "Flow fitting for mem-
brane-covered sensors (type 202811/30)", page 22.
NOTICE
The membranes may be damaged by high pressure.
Operating the sensors with increased pressure may cause the membranes to rip.
The sensors should be operated under as little pressure as possible, with the measurement media
able to flow freely. If this is not possible, the sensors can be operated under a constant pressure
according to the specifications in chapter 10 "Technical data", page 55. Fluctuations in pressure
must be avoided.
NOTICE
Air bubbles may lead to incorrect measurement results.
The presence of air bubbles in the measurement medium in front of the membrane may produce incor-
rect measurement results.
In order to ensure error-free measurements, the measurement media must be free of air bubbles.
NOTICE
Interruptions in the voltage supply may produce incorrect measurement results.
An interruption in the voltage supply (e.g. in interval operation) may produce incorrect measurement re-
sults. The sensors require a settling time period to determine the correct measurement.
In order to ensure error-free measurements, the sensors and transmitters must be permanently sup-
plied with voltage, even in interval operation.
NOTICE
Dry electrolytes may produce incorrect measurement results.
If there is no medium to measure when the membrane cap is filled, a build-up of salt on the inside of the
membrane may cause incorrect measurement results.
For sensors with electrolyte-filled membrane caps, the sensor fittings should be prevented from
draining or dry running.
NOTICE
Deposits on the membrane may lead to incorrect measurement results.
If there is no disinfectant (hydrogen peroxide or peracetic acid) in the measurement medium for more
than 24 hours, this will lead to incorrect measurement results due to deposits (biofilm) on the membrane.
Avoid operating the sensors with measurement medium which does not contain a disinfectant. After
operation in a disinfectant-free medium, a settling time period is to be expected. It may be necessary
to delay switching on dosing.

4 Mounting
18
NOTICE
Impurities may produce incorrect measurement results.
Using the sensors to measure media containing oxidants, reducing agents or corrosion protection agents
may lead to incorrect measurement results.
Oxidizing agents, reducing agents, corrosion inhibitors, and substances which result in cross sensi-
tivities with the sensors (see information in chapter 10 "Technical data", page 55) must be avoided
in the measurement medium.
NOTE!
If no disinfectant is dosed over a long period of time, the sensors must be disconnected from the trans-
mitter/controller, removed and stored correctly; please refer to chapter 7.3 "Storage", page 48.
