Water Chlorine Sensor (202630)

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.
