Process Conductivity Sensors
The Dilemma of Traditional Conductivity Electrodes
At present, the most commonly used conductivity electrodes in China are generally online bipolar electrodes.which are usually made of stainless steel, titanium metal, or platinum plated black, The bipolar electrode isusually suitable for measuring in low conductivity water bodies. When the conductivity value is greater than20mS/cm, the bipolar electrode will produce measurement errors and the measured value cannot bemeasured, There are also a small number of manufacturers who can produce guadrupole conductivityelectrodes, but the best materials can only use titanium metal, and the arrangement of titanium rods canonly be in series, The disadvantage of this electrode is that the titanium metal will corrode during freauentacid and alkali washing of the measuring pipeline, resulting in inaccurate measurement.
Therefore, how to solve the above problems, the technical implementation elements are:In order to overcome the shortcomings of the existing technologies mentioned above, the purpose of thisutlity model is to provide a four stage graphite conductivity electrode that can measure high conductivitywater bodies, is not afraid of acid and alkali corrosion, and can withstand high temperatures.
