"Non destructive testing is used extensively across a number of industries, where there is a need to detect anomalies and defects in engineered components, without destroying them. The most demanding applications are in equipment used in industries such as oil and gas, aerospace, and power generation, where components are safety-critical, of particularly high value and subject to extreme operating conditions. Non destructive testing, during manufacturing and service can identify, for example, cracks caused by manufacturing or material issues, delamination of surface coatings, porosity, and cracks caused by fatigue due to cyclic and thermal loads. To address a multitude of different application requirements, there are many different techniques used in non-destructive testing; these include ultrasound, magnetic-particle, liquid dye penetrant, visual, eddy current, and X-rays.Techniques based on magnetic disturbances induced in conductive materials by eddy currents (as discovered by Faraday in the 19th Century, and employed in non destructive testing commercially since the 1950s) are useful in a number of applications, including the detection of surface and near sub-surface defects in metal parts. However, the technology's capabilities have not kept pace with the advances in the components it is employed to evaluate. Manual liquid dye penetrant techniques have been in use since the late 19th century in similar applications. The process has high 'resolution' in skilled hands, and remains the mainstay of non destructive testing for surface defects in some of the most advanced engineered components. However, the technique has a number of disadvantages, including the subjective nature of interpretation of results, high operating costs, toxic consumables, lengthy testing times, and the need to thoroughly prepare the surface prior to testing.Using innovative electronics and analysis techniques, Eddysense is developing the next generation of capability in eddy current testing. Our technology will allow for detection of smaller defects, in a wider range of materials, than is currently possible with the state of the art. Where manufacturers and maintenance providers are currently reliant on the aged liquid dye penetrant technique, our technology will provide a much cleaner, safer and more reliable solution to the challenges of those involved in some of our most advanced engineering."

“无损检测广泛应用于许多行业，这些行业需要在不破坏工程部件的情况下检测异常和缺陷。要求最高的应用是在石油和天然气、航空航天和发电等行业中使用的设备，这些行业的组件对安全至关重要，具有特别高的价值，并且受极端操作条件的影响。例如，在制造和服务过程中，无损检测可以识别由制造或材料问题引起的裂纹、表面涂层的分层、孔隙率以及由循环和热载荷引起的疲劳引起的裂纹。为了满足多种不同的应用需求，在无损检测中使用了许多不同的技术；这些方法包括超声波、磁粒子、液体染料渗透、视觉、涡流和x射线。基于涡流在导电材料中引起的磁扰动的技术（19世纪由法拉第发现，自20世纪50年代以来用于商业无损检测）在许多应用中都很有用，包括检测金属部件的表面和近表面缺陷。然而，该技术的能力并没有跟上用于评估的组件的进步。自19世纪后期以来，人工液体染料渗透技术一直用于类似的应用。该工艺在熟练的工人手中具有很高的“分辨率”，并且仍然是一些最先进的工程部件表面缺陷无损检测的主要方法。然而，该技术有许多缺点，包括结果解释的主观性、操作成本高、有毒耗材、测试时间长，以及在测试前需要彻底准备表面。利用创新的电子和分析技术，Eddysense正在开发下一代涡流测试能力。我们的技术将允许在更大范围的材料中检测更小的缺陷，而不是目前的技术水平。在制造商和维修供应商目前依赖于陈旧的液体染料渗透技术的地方，我们的技术将为那些参与我们最先进工程的人提供更清洁、更安全、更可靠的解决方案。”
