Conductivity is a measure of a materials ability to conduct an electric current in solution. It is measured in milliSiemens or microSiemens depending on the number of ions (electrolyte) in solution. Two cell electrodes (measured in microSiemens) provide a simple method for conductivity measurement. These are typically used in applications such as ultrapure water, deionised water, reverse osmosis, and boiler water measurement. Four cell electrodes (milliSiemens) add in an extra pair of electrodes. The second pair of electrodes provides sensor diagnostic which compensates for build up on the electrodes. Typical applications include CIP, salinity, chemical concentrations, and condensate returns.
Temperature compensation is essential and is built into the electrode cell. Cell constants can vary from 0.01 to 20 depending on the application. Various process connections and cabling options are available depending on customer specific requirements.
