Industrial conductivity probes often employ an inductive method, which has the advantage that the fluid does not wet the electrical parts of the sensor. Here, two inductively-coupled coils are used. One is the driving coil producing a magnetic field and it is supplied with accurately-known voltage.
Much of the development of ECT as a nondestructive testing technique for industrial applications was carried out during World War II in Germany. Professor Friedrich Förster while working for the Kaiser-Wilhelm Institute (later the Kaiser Wilhelm Society ) adapted eddy current technology to industrial use, developing instruments measuring ...
Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of measuring the ionic content in a ...
Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
Then conductivity increases slightly up to the equivalence point volume, due to contribution of the salt cation and anion of the weak acid as it is formed from and the neutral acid (This changing contribution in case of a strong acid-strong base does not occur as in strong acids the anion is present all the time). After the equivalence point is ...
[2] [3] The experimental methods to determine the blend time in liquid include conductivity method and discoloration method. [1] [4] The conductivity method requires a conductivity probe to present in the target system, which make it an intrusive method because the existence of the probe might change the mixing efficiency of the mixing device ...
