CORROSION MONITORING

摘要

A system (100) for corrosion monitoring comprises first ultrasonic transducer units (4) for transmitting ultrasonic waves along a surface of an object (2), second ultrasonic transducer units (5) for receiving the transmitted ultrasonic waves, and a corrosion detection device (1) for processing transducer signals to detect corrosion of the surface (3) and for communicating corrosion data derived from the transducer signals to a remote station (20). The corrosion detection device (1) is arranged for communicating the corrosion data to remote station (20) only if the detected corrosion change exceeds a threshold, thus saving energy if no corrosion change is detected.
