  • Solar Light Towers for Remote Security

    Lights are the most important components of security systems. Well-lit locations are generally avoided by trespassers, because such areas can disrupt stealthy movements. The isolated nature of far-flung locations, such as military bases, mining sites, agricultural operations and manufacturing plants, can be made secure with solar perimeter lighting, coupled with other security devices. ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...

  • On the application of miniSoDAR technology to wind energy

    Introduction In the late 1990’s wind turbines with nacelle heights exceeding 60 meters were introduced to the wind energy community. Initially, wind prospecting and siting studies continued to use 50-meter wind towers and extrapolate the measurement to the nacelle heights. It was quickly determined that this approach was not sufficient for the placement of these tall turbines. The next ...
