ABSTRACT:
A calibration plug provides resistance simulation for calibrating toroidal conductivity sensors. This calibration plug includes a resistive element of predetermined electrical resistance coupled in series between electrical leads which may be engaged with a circuit element to form an electrical circuit. The toroidal sensor includes one or more toroidal coils defining a central bore extending therethrough, a cell factor, and a full scale conductivity value. The predetermined resistance of the resistive element is determined in accordance with the following equation:Resistance⁢⁢in⁢⁢Ohms=[geometric]⁢⁢cell⁢⁢factor⁢(of⁢⁢EC⁢⁢sensor)×1000Full⁢⁢scale⁢⁢conductivityvalue⁢⁢in⁢⁢millisiemens/cmand the calibration plug further includes indicia identifying one or more toroidal conductivity sensors for which the plug is configured.
