Leak testing method for seals, e.g. seals around articulations and linkages that are exposed to a hostile environment, whereby the signal of an eddy current probe within the seal is monitored to detect leak-induced changes
Leak-testing method in which a sealing membrane (4) is arranged around the transceiver coil (10) of an eddy current probe (8) that generates a high frequency magnetic field within an inner chamber (5). If a conducting test fluid enters the chamber the induced eddy currents generate a measurement sig...

| description | Leak-testing method in which a sealing membrane (4) is arranged around the transceiver coil (10) of an eddy current probe (8) that generates a high frequency magnetic field within an inner chamber (5). If a conducting test fluid enters the chamber the induced eddy currents generate a measurement signal that can be measured and evaluated.
Zur Dichtheitsprüfung von Bauteilabdichtungen gegen das Eindringen einer elektrisch leitfähigen Testflüssigkeit in einen von einer Dichtmembran umschlossenen Innenraum wird mittels einer außerhalb der Dichtmembran (4) angeordneten Sende-Empfang-Spule (10) einer Wirbelstromsonde (8) ein hochfrequentes Magnetfeld im Innenraum (5) erzeugt. Nach Eindringen der Testflüssigkeit in den Innenraum (5) liefern die dort induzierten Wirbelströme ein Messsignal, das erfasst und ausgewertet wird. |
