摘要： Detection of corrosion and other defects in piping is needed to prevent catastrophic pipeline failure. Sensors, systems and methods are provided to enable detection of such defects. These apparatus and methods are configured to characterize pipe protected by insulation and conductive weather protection. The sensors may utilize inductive and/or solid state sensing element arrays operated in a magnetic field generated in part by a drive winding of the sensor. Multiple excitation frequencies are used to generate the magnetic field and record corresponding sensing element responses. Relatively high excitation frequencies may be used to estimate the properties of the weather protection and sensor lift-off while lower frequencies may be used to detect internal and external pipe damage. Linear arrays may be moved to generate damage images of the pipe providing size and location information for defects. Two dimensional sensor arrays may be used to provide imaging without moving the sensor.

摘要： System and method for characterizing material condition. The system includes a sensor, impedance instrument and processing unit to collect measurements and assess material properties. A model of the system may be used to enable accurate measurements of multiple material properties. A cylindrical model for an electromagnetic field sensor is disclosed for modeling substantially cylindrically symmetric material systems. Sensor designs and data processing approaches are provided to focus the sensitivity of the sensor to localize material conditions. Improved calibration methods are shown. Sizing algorithms are provided to estimate the size of defects such as cracks and corrosion. Corrective measures are provided where the actual material configuration differs from the data processing assumptions. Methods are provided for use of the system to characterize material condition, and detailed illustration is given for corrosion, stress, weld, heat treat, and mechanical damage assessment.

摘要： A sensor system has an integrated sensor cartridge, and instrument, and an instrument side connector. The integrated sensor cartridge has a mechanical support, a flexible sensor array, and a rigid connector. The mechanical support is shaped to facilitate sensor measurements on a test object. The rigid connector has a mechanical connection and an electrical connection for simultaneous electrical and mechanical mating of the sensor cartridge to the instrument side connector. The flexible array has a connecting portion, a lead portion, and a sensing portion. The sensing portion is attached to the mechanical support, and the connecting portion interfaces with the rigid connector. The connecting portion may form the electrical connection of the rigid connector or may simply mate internally with the electrical connection. The instrument side connector is connected to the instrument which measures the response of the flexible sensor array. Test objects may include bolt holes, fillets, disk slots, and other types of parts or components.
