Conductivity: Water Quality Assesment - IJERT
www.ijert.orgThere are two types of conductivity sensors: electrodes (or contacting sensors) and toroidal or inductive sensors. Electrode sensors contain two, three, or four electrodes. The conductivity is directly proportional to the cell constant and inversely proportional to the resistance. The
THEORY AND APPLICATION OF CONDUCTIVITY
www.emerson.comcontacting sensors, the product of the cell constant and conductance is the conductivity. The walls of the tank or pipe in which the sensor is installed also influence the cell constant—the so-called wall effect. A metal (conducting) wall near the sensor increases the induced current, leading to increased
