FIC PW free chlorine sensors for drinking water

Amperometric free inorganic chlorine sensors FIC PW for drinking water

Measurement range:

  • 0.05 ÷ 10 ppm

FIC PW chlorine sensor for drinking water for measuring free inorganic chlorine in water, supplied with electrolyte, used in Etatron automatic water treatment plants. Highly pH dependent. The sensor cannot be used in water with: isocyanuric acid, surface-active substances (surfactants), flocculant, iron and manganese. A connecting cable is not included, a non-standard sensor holder is required (on request).

Design and operation of the closed-circuit ammeter FIC PW - is a closed galvanic cell (similar to a battery), which has a cathode (in gold or platinum) and an anode (silver or copper). For automatic temperature compensation of the readings of the electrodes, a liquid temperature sensor is integrated. The cell is filled with electrolyte and separated from the medium by a membrane, which prevents the loss of electrolyte and allows only the composition of the liquid to be measured to be measured, which is also a filter from unnecessary and harmful impurities. All that the membrane passes is a source of current generation on the sensor electrodes. The filtered membrane composition enters the electrolyte filling the sensor, where it 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 the water, the level of which was necessary to measure. A microcircuit is integrated in the housing, which processes the current coming from the electrodes and the built-in temperature sensor, converts suitable voltage for potential processing of the reagent by the controller into voltage (potential)
