A glimpse into the future of wind turbine maintenance


Wind turbines are playing a crucial role in the expansion of greener energy alternatives currently contributing around 30% of the UK’s total electricity generation. Like any rotating industrial application and machinery, timely and effi cient maintenance is critical for wind turbines. For example; understand the dynamic behaviour, establish a baseline performance to detect the early onset of failure of rotating parts. As with all condition monitoring, if machinery is left unchecked there will always be increased potential for more serious damage and disruption.


Condition monitoring specialist Sensonics are continually developing advancements in wind turbine blade health monitoring and their collaborations, along with the major players in wind turbine projects, are a good example of how they contribute to ensuring the giants of green energy continue to spin cleanly and effi ciently now and in the future. The latest example is their recent visit to the Crystal Rig ll Wind Farm near Dunbar in Scotland, as part of a collaborative team from Natural Power and the University of Huddersfi eld. The wind farm has an installed capacity of 138 MW and is managed by Natural Power, part of the Fred Olsen Group.


This UK government-funded project investigating blade health monitoring at the Crystal Rig wind farm holds immense promise for the wind energy industry. By leveraging the latest sensor technology, university expertise and real-world data collection, the project has the potential to revolutionise how we maintain wind turbines. By visiting the wind farm the project team were able to see the 2.3 MW Siemens turbines in action and discuss the monitoring strategy with the site personnel.


T57 at the Crystal Rig ll site has been fi tted with a range of sensing and data equipment from Sensonics to develop a database of measured performance data across a range of blade conditions.


The main objective of the project is to provide operators with ‘live’ blade data health through the monitoring of the main bearing only, then processing the data through specialised algorithms developed by the University of Huddersfi eld, combined with machine learning techniques.


The project has boosted the early detection of blade issues. Catching blade deterioration early reduces repair costs and improves turbine uptime, resulting in signifi cant fi nancial benefi ts for wind farm operators. This will also improve operational effi ciency; real-time blade health data allows for optimised maintenance schedules, minimising downtime and maximising energy production.


Proactive blade maintenance can extend the lifespan of wind turbines, delaying expensive replacements and maximising return on investment. Additionally, focusing on non-rotating parts for sensor placements simplifi es installation and reduces maintenance complexity.


The Crystal Rig ll project exemplifi es the power of collaboration between industry leaders like Natural Power, academic institutions like the University of Huddersfi eld and sensor specialists like Sensonics. By combining this expertise and the valuable resources, this project is paving the way for groundbreaking advancements in wind turbine health monitoring, representing a signifi cant step forward towards a future where wind turbine maintenance is more predictive and effi cient.

New all-in-one weather station unveiled at Meteorological Technology World Expo


R.M. Young Company (YOUNG) recently unveiled its newest weather sensor, the ResponseONE-PRO™, at the Meteorological Technology World Expo on September 24, 25, and 26, 2024. This newly designed all-in-one weather station allows users to easily access the internal weather sensors and fi lter for quick, convenient, and cost-effective maintenance.


The YOUNG ResponseONE all-in-one weather station allows users to gather wind speed and direction, temperature, humidity and pressure accurately and reliably from a single source with a minimal footprint. There are options for add-ons as well, including a compass or a precipitation gauge. These components and systems work together seamlessly to provide accurate and reliable weather data. The sensors measure atmospheric variables and transmit them as a single output string.


To further build upon this tried-and-true instrument, YOUNG revealed its updated design, the ResponseONE-PRO, for the fi rst time at the Meteorological Technology World Expo in Vienna. The ResponseONE-PRO features an access port, so users can easily remove and replace the protective fi lter and internal sensor module. This feature enables users to restore the performance back to factory standards without the need to return to the manufacturer, which can be time-consuming and costly.


The ResponseONE-PRO was specifi cally engineered to meet the demands of marine data buoy applications, enabling sensor replacement without the need to return the entire instrument to the manufacturer for repairs or calibration. For the past three years, it has been deployed in harsh marine environments on ocean buoys, consistently providing accurate and reliable data.

New biocompatible potentiometric pH sensor for accurate analysis in a wide range of applications


After extensive development in its R&D laboratory, Linxens has launched a pH sensor on a fl exible substrate that is adapted to the specifi c needs of its customers, while offering an economical and effi cient alternative to conventional devices.


For More Info, email: email:


Accurate pH measurements enable us to monitor a wide range of different applications ranging from ensuring the quality and safety of food and beverages to environmental monitoring of water and soil - all of which can be analysed with a simple pH measurement. Accurate pH data is crucial in a wide variety of applications to ensure the quality, safety and effi ciency of products and processes. Traditionally, pH measurements were only performed by using unreliable and inconstant pH strips, or by using electrodes in a laboratory with a pH meter or photometer – which also has signifi cant limitations.


For More Info, email: email:


Linxens’ unique and patented pH sensor provides a reliable, versatile and cost-effective solution. This


potentiometric sensor utilises carbon nanotubes and a conductive polymer. It remains highly effective, even in highly oxidising environments and can collect and analyse pH in the harshest environmental conditions.


Catheline Ramsamy, Ph. D, Sales Manager EMEA at Linxens Healthcare commented, “Thanks to its expertise in the design and manufacture of electronic solutions, Linxens is able to offer high-quality products that meet the needs of its customers. The pH sensor is an example of Linxens’ commitment to innovate and provide cutting-edge solutions to meet current and future challenges.”
