Current status and characteristics of the four-electrode conductivity sensor
Four electrode conductivity pool by two current electrode and voltage electrode, electrode coaxial electrode voltage and current, when measuring the liquid to be tested in two current between the electrode gap, impose an ac signal current electrodes at both ends and by electric current, establish the electric field in the liquid medium, two voltage electrode voltage induction, make two voltage at the ends of the electrode voltage constant, by two current electrodes has a linear relationship between current and liquid conductivity.
In order to meet the needs of Marine research and development, China's national ocean technology center li Jianguo to open four-electrode conductivity sensor is a research and development, successfully developed a four-electrode conductivity sensor used in seawater conductivity measurement, its performance index has reached the international advanced level, measurement range of 0 ~ 65 mS/cm; The measurement accuracy is ±0.007 mS/cm.
At present, the mature four-electrode conductivity sensor has a measuring range of 0-2S/cm, and different electrode constants have different measuring ranges.
The four-electrode conductivity sensor has the following characteristics: 1) the current electrode is separated from the voltage electrode, and the current electrode is powered by a constant current source, which effectively avoids the influence of polarization impedance;2) High sensitivity and strong anti-pollution ability;3) The four-electrode conductance cell has the characteristics of ultrastructure, large diversion space and short distance, which is suitable for long-term field measurement.
