Inductive (Torodial, Electrodeless) Conductivity Analyzer
2016-05-27 13:03:00
Description:
One way to make a conductivity measurement is Inductive Conductivity (also called Torodial or Electrodeless). In this type of measurement the sensing elements (electrode coils) of a sensor do not come in direct contact with the process. The Inductive Conductivity method is especially suitable for high conductivity measurements. The analyzer works with a sensor with two toroidal transformers built in. An AC current induces a voltage in the process sample that results in a current in the sample. The strength of this current is proportional to the conductivity of the sample following Ohm's law.……
