Short description
The JUMO TecLine C12 is a membrane-covered amperometric sensor and is 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 temperature-compensated current signal 4 to 20 mA 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 (See “Suitable indicating devices/transmitters/controllers “, page 10 of the data sheet document). They provide the voltage required for supplying the sensors and allow for easy calibration of the measuring system.
