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.
