METHOD AND APPARATUS FOR MONITORING CORROSION AND REPORTING SAME ACCORDING TO ACCEPTED INDUSTRY STANDARDS

摘要

process and apparatus for the use of a piezo electric crystal to monitor and report on treaty is recognized as non conforming to an industry standard.the invention relates to a method and a system for monitoring the corrosion in the corrosive atmosphere.understanding and implementing the steps up to the atmosphere in a crystal under a metallic substance by corrosion, and having a vibration frequency is known, to measure the change of vibration frequency due to the corrosion of the material attacked by corrosion during each interval of a plurality of time intervals.including a reference interval, followed by at least one measurement interval and generate a signal representative of the thickness corresponding to the thickness change of the measured corrosion rate during the measurement interval; and converting the signal of the depth of corrosion in a measurement interval reference signal representative of the thickness of the accumulated during the internal corrosionervalle reference. the invention is also preferably correct the frequency change measured during each interval to account for any deviation in the temperature in the atmosphere from a temperature standard.the invention also includes, preferably, a humidity sensor for a pulse to transmit alarm to the user if the relative humidity is greater than a predetermined limit, or if the relative humidity changes over a period of more than a predetermined limit.according to the invention, a device is used in corrosive environments such as space measurement and control of industrial processing, motor control centers, electrical rooms, clean rooms, semiconductor, electronics production no commercial data centers, museums,library and archival storage space.
