uSing Data to Deliver preDictive maintenance


For generations, maintenance professionals have used preventive maintenance to avoid equipment failures and turned to reactive maintenance when assets failed. With the emergence of Industrial Internet of Things (IIoT) technologies, maintenance professionals can now connect tools, software and sensors to collect, store and analyse multiple data sources in one place. The pandemic accelerated investment in technologies that make remote monitoring possible. The technology enables reliability and maintenance teams to meet up- time requirements no matter how fluid on-site staffing might be. The trend for remote monitoring will continue, with small scale


operations turning to remote condition monitoring services. Artificial intelligence (AI) and


machine learning (ML) have held the promise to quickly identify trends and adapt quickly to changing operational conditions. Software armed with prescriptive analytics is finally meeting up with modern condition monitoring hardware to spark a revolution in the use of AI/ML in maintenance operations. Now a new race has emerged to


pair that hardware and software with ML and AI algorithms. Companies, like Fluke, are working to combine technologies so that the software can identify trends, recognise data patterns and make specific recommendations for equipment maintenance.

Digital Si SpeeDS integration of critical equipment meaSurementS


The accelerated uptake in digital measurement solutions for industrial applications can save time and money, whilst facilitating a shift towards predictive maintenance for systems. Although modern measurement digital devices are typically not fit-and-forget solutions, the increase in digital measurement solutions paves the way for verification technologies that can help to reduce the maintenance burden on personnel, without compromising on accuracy or reliability. Digital SI (International


System of Units), an initiative created as part of the industry 4.0 revolution, relates to the creation of a globalised system to transmit calibration certification information electronically. This is critical as the exchange of data and the data itself are the basis of highly automated industrial processes. The system ensures measurement traceability from all calibrations performed and enables sharing of information in a paperless manner. This speeds up the integration of measurements that can be performed using critical test equipment as part of an integrated factory enhancing maintenance efficiency and plant efficiency. “The tests we have faced within the last 24-36 months is delivering a


growing awareness among top management that fundamental changes in maintenance best practice need to occur in order to protect the bottom line,” says Feenstra. “This is music to the ears of progressive industrial managers who have


been advocating for investments to improve efficiencies and reliability of systems. Now is the time to make the case to adopt innovative technologies, tools, and processes to ensure your company maintains a competitive edge and thrives in this new environment.”

measuring at high speed, even on dark or rough surfaces


M


icro-Epsilon has expanded its confocalDT range of confocal controllers with two new industrial-grade controllers for distance and thickness measurements


on a variety of materials, including dark or rough surfaces. The confocalDT 2465 single channel controller and the confocalDT 2466 dual channel controller offer extremely high light intensity at high measuring rates up to 30kHz. In terms of the size and performance of its product


portfolio, Micro-Epsilon is a leader in the field of confocal measurement technology. The confocal measurement principle is designed for high accuracy, non- contact displacement, distance and position measurement against any surface: solid, transparent, polished mirrored surfaces, low reflective matt surfaces and even liquids. If a surface is transparent, a one-sided thickness measurement can be achieved with inbuilt correction for the material refractive index. The confocalDT 2465 and confocalDT 2466 controllers


are suitable for use with all confocal chromatic sensors from Micro-Epsilon. The controllers are extremely light-intensive, which enables good signal stability and therefore stable measurements, even on dark or rough surfaces. Very fast measurements are possible on shiny targets. The confocalDT 2465 is designed for one measuring


channel. With the confocalDT 2466, two measuring channels can be processed via one controller, which offers a price advantage for multi-channel applications. Measurement acquisition is synchronous and can be carried out while exploiting the full measuring rate for both channels. Quite often, confocal sensors are selected when laser


triangulation or other optical sensors are not accurate or stable enough on the surface being measured. In addition, confocal sensors have an extremely small spot diameter, typically a few microns and measure in the vertical plane, so do not suffer from shadowing of the reflected light. This also enables measurement into small bores and holes. Almost all industries benefit from this measurement


principle as it can be used in both R&D and in-process measurements. In particular, the semiconductor, micro lens, automotive parts, medical, glass and MEMS industries use this sensor technology in many ways. As with previous models, Multi-Peak controllers are also


available for the confocalDT 2465 and 2466. These enable layer thickness measurements of up to five transparent layers. Integration and commissioning (interfaces, ASCII commands, parameter set up, etc.) are identical to the existing confocalDT 242x controllers, as are the controller dimensions. Due to a user-friendly web interface, no additional software


is required to configure the controller and the sensors. Data output is via Ethernet, EtherCAT, RS422 or analogue. Optional interface modules are also available which enable data output via Profinet or EtherNet/IP.
