The Honeywell 5000TC toroidal (inductive magnetic field cells) operate on a different principle than the traditional contacting electrode cell. The device sends an alternating current of known value through the primary coil which creates a magnetic field and induces a current in the process liquid. This in turn, induces a current in the pickup coil which is directly proportional to the conductivity of the liquid. These toroidal cells thus eliminate direct contact between the coils and the solution eliminating potential maintenance problems.
These cells come with a 1 ½” diameter bore which minimizes rough surfaces and flow impedance and a 1000Ω Platinum Resistance Temperature Detectors (RTDs) which ensures proper temperature compensation.
