FIELD: machine building.
SUBSTANCE: group of inventions relates to equipment housing integrity diagnostics facilities. Disclosed is method, according to which in process plant first valve body impedance measurements sequence is recieved in response to first frequency, storing said first impedance measurements sequence, receiving second valve body impedance measurements sequence in response to second frequency, storing said second impedance measurements sequence, comparing first and second impedance measurements sequencies and generated indication on valve body integrity loss, if first impedance measurements sequence is offset from second impedance measurements sequence.
EFFECT: technical result is increasing in accuracy of equipment housing loss of integrity determining.
