Measuring Principle

The amperometric sensor is based on the conversion of the measuring variable chlorine in electrical current. Two electrodes covered by an electrolyte are in contact to the medium via a membrane. It has a platinum working electrode and a silver halogenide coated counter or reference electrode. The chlorine compounds contained in the medium diffuse through the membrane. The constant polarisation voltage between the two electrodes instigates the electrochemical reaction of the chlorine compounds on the working electrode. The resulting current is measured as a primary signal (amperometric measurement principle). It is proportional to the chlorine concentration within the sensor’s operating range and only slightly pH dependant for this type of sensor. The primary signal is converted by the amplifier electronics of the sensor into a 0 ... 5 μA output signal which is displayed by the transmitter.

Measuring Principle Total Chlorine
Application Potable water,Process water, Waste water, pools
Characteristic Amperometric measurement of total chlorine.
Measurement range 0,1 - 10ppm total chlorine; pH 6,5 - 9,5
Measuring principle - Total chlorine consists of free chlorine (HOCl, OCl) and bounded chlorine (chloramines).
- A constant polarisation voltage between working and counter electrode instigates the electrochemical reaction.
- Only slightly pH dependent.
Design Closed amperometric two electrode sensor for continuous measurement of total chlorine.
