  • DETECTION OF CRACKS ON METAL BELLOWS OF VALVES
    Publication number: 20130008252
    Abstract: The present disclosure relates to a method for detecting a damage or contamination of a valve bellows, comprising the steps of: causing the valve bellows to oscillate, sensing the oscillations with a sensor and outputting a sensor signal generated by the oscillations, and comparing at least one sensor signal value with at least one reference value. The disclosure further relates to an apparatus comprising a valve with a valve bellows, a sensor for sensing oscillations of the valve bellows and for outputting a sensor signal generated by the oscillations, and a comparator circuit, such as a microprocessor, for comparing at least one sensor signal value with at least one reference value.
