Explain the working of toroidal conductivity sensor and what are they used for
This sensor can detect if a solution is capable to conduct electrical current, Toroidal conductivity sensors consist of two toroidal coils inside an inert plastic case (these toroidal coils are how the “toroidal” sensor gets its name). One toroid emits an electric field, and the other detects a small induced electric current proportional to the number of ions present (this induced current is why toroidal sensors may also be called “inductive” sensors). The two toroids form a transformer whose coils are interconnected by the resistance of the surrounding electrolytic solution
