Non-wetted electrodes with high tech ceramic liner

krohne-273-09-3014The Optiflux 7300 is said to combine the advantages of non-wetted capacitive electrodes, a ceramic liner and the IFC 300 converter. This electromagnetic flowmeter can be used for noisy applications, low conductivities, mediums tending to form an insulating film, applications with high vibrations, and oxidising, abrasive and toxic mediums. Instead of conventional electrodes that have a direct contact with the process liquid, Optiflux 7300 has a non-contacting capacitive signal pick-up. The electrodes are designed as large-area capacitor plates, mounted behind the ceramic liner. Because the electrodes have no contact with the medium, unwanted catalytic action with metallic parts is eliminated. A second benefit is that the insulation of electrodes no longer forms a risk. In case of a medium that tends to form a non-conductive surface coating on the tube wall, the signal pick up between medium and electrodes will not be interrupted. The smooth and pore free ceramic tube construction does not leak and is CIP SIP resistant, making it highly suitable for hygienic applications in for example the food & beverage and pharmaceutical industry.
