Amperometric open system offline cells to the measure free chlorine in the system with 0÷10 mg/lt reading (ppm) with incoming manual flow adjustment, provision for housing two electrodes, temperature probe and proximity switch. with self cleaning glass balls providing continued maintenance of the cell.

High performance and reliable ion selective membrane sensors providing accurate readings which the controller is dependant upon to ensure complete stable control of the dosing system, the robust design of our sensors requires minimal maintenance and therefore ideal for all types of chemical dosing systems that requires continued stability within water treatment applications including high demands found in most environments.

Measurement of chlorine Cell

 

The standard amperometric sensor consists of two electrodes (anode and cathode) these measure a change in current caused by the chemical reduction of the chlorine through a membrane over the cathode at the tip of the sensor, a voltage applied to the cathode reduces the chlorine to chloride the process consumes electrons which come from a second electrode (the anode) inside the sensor, the number of electrons consumed at the cathode, is directly proportional to the concentration of chlorine in the sample. These types of chlorine sensors are fairly low maintenance although they do require periodic cleaning to wash away solids that slowly accumulate on the membrane providing continuous and low running costs over many years with replacement membranes available.    

 

All our chlorine controllers incorporate control relays as well as a (0) 4-20mA signal. Depending on which model of controller - these can be used to control a piece of control equipment such as a pump or solenoid valve. Often these pieces of control equipment can be controlled proportionally that is - causing the device to speed up, or dose faster / slower depending on the deviation from the desired set-point.
