Abstract
In a sensor such as a pH sensor, a bundle of relatively long, thin and soft cleaning filaments is anchored next to the pH electrode. A bluff body, which may be the reference electrode is positioned upstream of the bundle so as to create liquid vortices which move the free ends of the fibres in an effective cleaning action over the sensing surface of the pH electrode.
