Uppfinningen beskrivs närmare nedan med hjälp av ett föredraget utföringsexempel.The invention is described in more detail below with the aid of a preferred embodiment.
Vid det föredragna utföringsexemplet av uppfinningen består sättet för rengöring av elektroder i mätutrustningar i att elek- troderna med sin beläggning utsätts för en sågtandspuls med följande specifikation. Från en potential från -1,5 V så skall potentialen falla med en hastighet av en 1 V/s till 0 V för att sedan så fort utrustningen klarar återgå till -1,5 V. Detta upp- repas tillräckligt många gånger för beläggningens avlägsnande och vanligtvis sker upprepningen cza 20-60 gånger beroende pà typ av beläggning.In the preferred embodiment of the invention, the method for cleaning electrodes in measuring equipment consists in that the electrodes with their coating are exposed to a sawtooth pulse with the following specification. From a potential from -1.5 V, the potential must fall at a speed of 1 V / s to 0 V and then as soon as the equipment is able to return to -1.5 V. This is repeated enough times for the coating to be removed. and usually the repetition occurs cza 20-60 times depending on the type of coating.
Den nya metoden utgörs såsom nämnts ovan av en puls som upp- repas. När pulsen genereras så bildas en mekanisk pàverkan av beläggningen samt en vätgasutveckling på elektrodytan. Denna gasutveckling som utgörs av vätgas, gör att beläggningen lossnar och knuffas iväg av gasen. För att sedan få elektroden att bli normaliserad, dvs ej få en polarisering, så sjunker potentialen till 0 V med en långsammare hastighet än vid pulsens bildande, för att sedan avslutas med 0 V såsom slutpotential.As mentioned above, the new method consists of a pulse that is repeated. When the pulse is generated, a mechanical effect is formed by the coating and a hydrogen evolution develops on the electrode surface. This gas evolution, which consists of hydrogen gas, causes the coating to come loose and be pushed away by the gas. In order to then cause the electrode to become normalized, ie not to have a polarization, the potential drops to 0 V at a slower speed than during the formation of the pulse, and then ends with 0 V as the final potential.
