Product Details

Inductive conductivity measurements from Inductive conductivity sensors (also called toroidal sensors) are used in applications that are susceptible to high fouling/coating, metal corrosion, high conductivity, and percent concentration due to the fact that their sensing elements (electrode coils) don’t come into direct contact with the process. These two matched (identical) coils are encapsulated in PP, PFA or PEEK protecting them from the adverse effects of the process, making them suitable for the following applications:
High conductivity
Fouling /coating (dirty applications)
Percent concentration (e.g. brine, cleaning solutions)
Processes susceptible to metal corrosion
Clean-in-Place (CIP), etc.

Technical Features

Wide Measuring Range : Aumeascon’s Inductive Conductivity Sensors measure range is up to 2,000,000 microSiemens/cm. A built-in PT1000 resistance temperature detector (RTD) compensates the measured conductivity for changes in process temperature, max temperature is up to 180℃.

Low Maintenance Design : The inductive conductivity sensor design eliminates polarization and electrode coating problems that commonly affect conventional contacting electrode-type conductivity sensors.

Withstands Harsh Environments : The inductive conductivity sensor is available in sanitary (CIP) flange style and convertible styles in PFA, polypropylene(PP) and PEEK material. Selected sensors can withstand high pressures and temperatures.

Long life under harsh industrial conditions : Constructed with erosion and abrasion-resistant PEEK (Poly Ether Ether Ketone), the AM-D-ICS has excellent chemical resistance in all solutions with the exceptions of fluoric acid or oxidizing concentrated acids. For stronger chemical resistance, PFA (Teflon) material is available for applications in hydrofluoric acid and oxidizing concentrated acids (e.g. nitric, sulfuric, oleum).

Versatile Mounting Styles : Sensors can be installed using different mounting styles – immersion, insertion, union, and sanitary.

Accuracy in fouling, coating, and corrosion : The AM-D-ICS has an accuracy of 1% of reading for any conductivity value (whether measured in rinse water or in concentrated acids).
