FIELD: instrumentation. SUBSTANCE: invention is meant for cleaning of electrodes of electric contact transducer from fouling in process of usage in liquid media without dismantling of transducer and break of tightness of joints. Electrode of transducer located in insulator has outer helical surface contacting working medium. This surface is mated to inner helical surface of bushing placed immobile in insulator. Bushing has longitudinal cut and lateral ring groove in outer surface. Spring washer is put into groove. Electrode, bushing and washer are manufactured from corrosion resistant metal. Metal of bushing is harder than that of electrode. EFFECT: improved operational efficiency of electric contact transducer. 3 cl, 1 dwg
