What is the conductivity cell?
conductivity Cell is a device that consists of electrodes that feel the electrical conductivity of the substance such as water. Common configurations include two electrode cells and four electrode conductivity cells. The main feature that distinguishes each type is the cellular constant of the conductivity cell, identified as the size of the electrode of the letter, the distance between each and the pattern of the electric field present determines this cell constant. It is higher for cells with small electrodes that are distributed far apart and are lower for those that have larger electrodes deployed closer to each other.
To obtain conductivity reading, cell constant and material conductivity must be multiplied. The effect of the marginal field must also be taken into account into the equation, which is also simplified by the design of the solution in which electrical conductivity is known. Calibration of the probe with a cell conduction cell can be explained by an unknown cell, which changes with an aging electrode. Reading is also adapted to real when performing measurementsOU value based on the ambient temperature. Available in DIP or flow configurations, cells can be made of glass or epoxy. Some are not affected by marginal fields, especially if the measuring field remains inside the body of the electrode. Most types of conductivity meters are supported by the configuration of two electrodes.
Another popular type of conductivity is the version of four electrodes. This design makes measurement easier because there are fewer errors related to polarization or pollution of electrodes. The current does not flow in the measuring circuit, so that the voltage is measured precisely through the internal rings of the device. Alternating streams streaming the outer set of rings on the cell. With this design of the flow cell of the conductivity, a variety of conductivity can be measured.
conductivity The cell is only one component in the measuring system. The user must also have a transmitter and control for the signal fitness as well as the connecting cable to measure the conductivity. The whole system can be behindPlay everything, complete with a microprocessor that helps automate the conductivity measurement process. In addition to temperature compensation, the cell should also be used with an automated selection method and conversion factors that represent solutions different from natural or salty water.
