These membrane-covered amperometric sensors are used to measure
the concentration of free chlorine. The following anorganic
chlorination agents can be measured: chlorine gas (Cl2),
electrolytically generated chlorine, sodium hypochlorite (NaOCl,
chlorine bleaching solution), calcium hypochlorite (Ca(OCl)2), or
chlorinated lime (Ca(OCl)Cl).
The sensors are not suitable for detecting the absence of free chlorine.
The sensors' integrated electronics provide a temperaturecompensated current signal (4 to 20mA)
for the variant with an analog
output signal, and a Modbus RTU signal for the variant with a digital
interface. A downstream device (indicator, controller, recorder, PLC,
etc.) is used for calibration.
The sensors can be connected directly to various indicating
devices/transmitters/controllers. They provide the voltage required for
supplying the sensors and allow for easy calibration of the measuring
system.
