FIC PW free chlorine sensors for drinking water
Measurement range:
- 0.05 ÷ 10 ppm
Chlorine sensor FIC PW for drinking water for measuring free inorganic chlorine in water, supplied with electrolyte, used in automatic Etatron water treatment stations. High dependence on pH level. The sensor cannot be used in water with: isocyanuric acid, surfactants, flocculant, iron and manganese. Connecting cable not included, non-standard holder required sensor (on request).
The design and operation of the closed-type amperometric sensor FIC PW is a closed galvanic cell (like a battery), in which there is a cathode (made of gold or platinum) and an anode (silver or copper). For automatic temperature compensation of electrode readings, built-in sensor liquid temperature. The cell is filled with electrolyte and is separated from the measured medium by a membrane that prevents the loss of electrolyte and passes only the composition of the measured liquid necessary for measuring, also is a filter from unnecessary and harmful impurities. Everything that the membrane passes is a source of generation current on the sensor electrodes. The filtered membrane composition enters the electrolyte filling the sensor, where decomposes at the cathode. The formed ions enter the anode, where they are oxidized - a current arises, proportional to the concentration of the analyte in water, the level of which was to be measured. Into the case a microcircuit is built-in that processes the current coming from the electrodes and the built-in temperature sensor, converts it into voltage (potential) suitable for handling reagent dosing by the controller
