摘要： Concrete can be one of the most durable building materials where consumption is projected to reach approximately 40 billion tons in 2017 alone. Despite this the testing of concrete at all stages of its life cycle is still in its infancy although testing for corrosion is well established. Further many of the tests today are time consuming, expensive, and provide results only after it has been poured and set. Accordingly, by exploiting self-contained wireless sensor devices, which are deployed with the wet concrete, the in-situ curing and maturity measurement data can be established and employed together with batch specific concrete data to provide rapid initial tests and evolving performance data regarding the concrete cure, performance, corrosion of concrete at different points in its life cycle. Such sensors remove subjectivity, allow for rapid assessment, are integrable to the construction process, and provided full life cycle assessment.

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： A method of measuring the amount of corrosion of a target material caused exposure to a fluid, over a period of time, utilizing a corrosion measuring device, including a resonator having a first surface area made of a material having a corrosion profile like that of the target material and having a second surface area made of material having a corrosion profile unlike that of the target material; and a transducer assembly, positioned to drive the resonator and sense resultant resonator motion, thereby producing a sense signal. In the method, the resonator is exposed to the target fluid over the period of time and the sense signal is analyzed over the period of time to determine changes in how the resonator responds to being driven by the transducer assembly, over time.

摘要： Wide-angled incoherent millimeter or sub-millimeter electromagnetic waves from an extended active source are used to probe substrates and their protective coatings or outer layers, such as paint or thermal insulation. The incoherent waves provide dispersion and angular variation with respect to angular incidence to the substrate. Illumination of the substrate permits differentiation between un-corroded and corroded sections of the sample because reflectivity, emissivity and/or transmissivity from the substrate or protective coating various according to its homogeneousness. A detector/camera is arranged to identify and resolve differences in detected power within an observed frequency range of the area under test, with this contrast in power being relative to either adjacent areas or anticipated reference levels. The power differences therefore signify the presence or lack of corrosion or, indeed, the presence of anomalies within or on the substrate or in or under the protective coating or layer applied to the substrate.

摘要： A remote terminal unit for use in monitoring a metallic pipeline can take an electrical measurement at the pipe and transmit the measurement in a modulated signal to a main measurement unit located along the pipe and distant from the remote terminal unit. The electrical measurement is taken at regular time intervals between a reference electrode electrically connected to the pipe and a coupon composed of a sacrificial corrosion material in order to monitor the pipe for possible corrosion. The electrical measurement is modulated with a low frequency carrier signal for transmission along the pipe, eliminating the need to take the measurements directly at physical locations along the pipe.

摘要： A permanently installed monitoring system for corrosion under insulation (PIMSCUI) and a method for performing the monitoring of said system are provided. The objective of the invention by a fiber optic cable permanently mounted between walls of a pipeline and pipeline insulation surrounding the pipeline and placement of acoustic emitters along the length of the pipeline in mechanical contact with the optical fiber. The acoustic emitters send a pulsed acoustic signal towards the pipeline which is received by the optical fiber, the acoustic signal subsequently travels through the pipeline wall, reflecting from the inner diameter of the pipeline before the reflected pulse is received at the optical fiber.
