Lifetime testing of passive, wireless sensors for demanding environments

Inductosense是布里斯托尔大学超声波和无损检测小组的副产品。我们开发了紧凑型、无线、无电池传感器，用于监测管道的腐蚀或侵蚀。我们的技术使任何人都能快速从传感器（或机器人车辆）获取数据，并将数据数字化并进行远程分析。传感器还可以在材料层（如涂层或包层）下工作，无需在测量之前将涂层从管道上移除。Inductosense已经在油气行业产生了吸引力，现在已经在全球范围内的陆上设施中部署了传感器，如化工厂、天然气厂和炼油厂。我们现在对我们的传感器是否能应用于海底产生了浓厚的兴趣，例如用于立管、海底管道等结构。在这些更苛刻的环境中，如果传感器发生故障，更换传感器就不那么容易了，因此长寿命（理想情况下与结构相匹配）是必不可少的。我们希望了解传感器在如此恶劣的环境下的使用寿命，并能够定制我们的传感器和技术以适应这种环境。”

"Inductosense is a spin-out from the Ultrasonics and Non-Destructive Testing Group at the University of Bristol. We have developed compact, wireless, battery-free sensors for monitoring corrosion or erosion in pipework. Our technology enables anyone to take the data from the sensors quickly (or a robotic vehicle to take the data) and for the data to be digitised and remotely analysed. The sensors also work underneath layers of material, such as coatings or cladding, eliminating the need to remove the layer from the pipe before taking a measurement.Inductosense has generated traction in the Oil&Gas industry and now has sensors deployed world-wide on onshore structures such as chemical plants, gas plants and refineries. We are getting lots of interest now in whether our sensors could be applied sub-sea - eg to structures such as risers, sub-sea pipeline. In these more demanding environments it would not be so easy to replace a sensor if it were to fail, so a long lifetime (ideally matching that of the structure) is essential. We want to understand what the lifetime of our sensors could be in such a harsh environment and also be able to tailor our sensors and technology to be suited to it."
