FIC free chlorine sensors
Measurement range:
- 0.05 ÷ 2 ppm
- 0.05 ÷ 20 ppm
- 0.05 ÷ 200 ppm
FIC chlorine sensor for measuring inorganic free chlorine in water, supplied with electrolyte, used in automatic water treatment stations ETATRON D.S. (Italy). For an accurate reading, the operating pH value must remain constant. The sensor cannot be used in water with: isocyanuric acid, surfactants, flocculants. The connecting cable is not included.
The design and operation of the closed-type amperometric sensor FIC is a closed galvanic cell (similar to a battery), which contains a cathode (made of gold or platinum) and an anode (silver or copper). For automatic temperature compensation of electrode readings, a liquid temperature sensor is built in. The cell is filled with electrolyte and is separated from the measured medium by a membrane, which prevents the loss of electrolyte and only allows the composition of the measured liquid to be measured, and is also a filter from unnecessary and harmful impurities. Everything that the membrane passes through is a source of current generation at the sensor electrodes. The filtered membrane composition enters the electrolyte filling the sensor, where it decomposes at the cathode. The resulting ions enter the anode, where they are oxidized - a current is generated that is proportional to the concentration of the analyte in the water, the level of which had to be measured. A microcircuit is built into the case, which processes the current coming from the electrodes and the built-in temperature sensor, converts it into a voltage (potential) suitable for the controller to process the dosage of reagents
