INTEPS - INtegrated optical ThErmal Phosphorescence System

传感器涂层系统有限公司(SCS)正在开发一种用于在恶劣工业应用中测量温度的创新技术。这是一项独特的热成像技术，适用于发电和航空航天等高价值市场。这项技术是基于SCS开发的一种智能记忆材料，它被用作待测部件表面的油漆或涂层。然后将涂覆的组件用于暴露在高温下的标准操作条件。在这一过程之后，一旦组件冷却下来，就会用同样由SCS开发和保护的激光探测仪进行讯问(专利正在申请中)。根据材料的发光特性，通过执行复杂的校准方法，可以测量组件过去的最高温度。校准方法依赖于测量涂层材料的寿命衰减(LTD)，该寿命衰减可以直接与涂层的过去最高曝光温度相关。SCS已经开发了一种定制的光学测量系统来执行这些LTD测量。最近的研究表明，额外的光谱测量可以极大地提高温度精度。SCS已经开发了用于光谱测量的单独仪器，目前正用于商业项目。然而，由于每个测量点需要测量两次，因此整个测量过程现在相当长，而且还可能受到空间误差的影响。因此，该项目的目标是将两个测量系统(LTD和Spectra)整合为一个系统，并同时执行两个测量。这将有效地减少50%的测量时间，对于大型工业项目来说，这可能需要几天的时间。操作成本也将降低，空间精度公差引起的测量不确定度也将消除。对于这个项目，SCS期待着与NPL合作，并利用他们的专业知识和最先进的设施和设备。

Sensor Coating Systems Ltd (SCS) are developing an innovative technology for measuring temperatures in harsh industrial applications. This is a unique thermal mapping technology for high value markets such as power generation and aerospace industries. The technology is based on a smart-memory material that has been developed by SCS and it is applied as a paint or a coating on the surface of the components to be measured. The coated components are then used in standard operating conditions where they exposed to high temperatures. After the process, once the components have cool down, they are interrogated with a laser-probe instrument also developed and protected by SCS (patent pending). From the luminescence properties of the material and by performing a sophisticated calibration method, the past maximum temperature of the component can be measured.The calibration method relies on measuring the Lifetime Decay (LTD) of the coating material, which can be directly corelated to the past maximum exposure temperature of the coating. SCS has developed a bespoke optical measurement system to perform these LTD measurements. It has more recently shown that additional spectral measurements can greatly enhance the temperature accuracy. Separate instrumentation for spectral measurements has been developed by SCS and is currently in use for commercial projects. However, the overall measurements process is now considerably longer and can also be subject to spatial inaccuracies, as each measurement point needs to be measured twice.The objective of this project is therefore to integrate the two measurement systems (LTD & Spectra) into one and perform the two measurements simultaneously. That would effectively reduce the measurement time by 50%, which can be several days for large industrial projects. Operational costs will also be reduced and measurement uncertainty due to spatial accuracy tolerances will be eliminated. For this project SCS is looking forward to collaborate with NPL and take advantage of their expertise and state-of-the-art facilities and equipment.
