  • The future of leak detection starts today

    For many water engineers the day in the office begins with a look at the screen. They can analyse the results of the nightly measurements of their fresh water pipelines in a few minutes and make important decisions for the day. Are there any new leaks in the system? Using the information found, the water engineer can send his workers to precisely those points that the leak detection system has ...

  • Forget big data! Collect the right data

    The term big data is everywhere nowadays, but what does it actually mean? According to a definition provided by Google, big data is ‘extremely large data sets that may be analysed computationally to reveal patterns, trends, and associations.’ Sounds great, right? In theory, yes. Through big data, businesses can have a greater overview of their operations than ever before, allowing ...

  • HAV mis-measurement – to no standards whatsoever…

    Misunderstanding Hand Arm Vibration monitoring marketing material can put hands and safety policies at risk. Caveat emptor. We are regularly asked about new vibration measurement technology, particularly re the latest hand-held, glove or wrist mounted transducers that are presented as the latest assessment improvements. Whilst they may be useful tools, unfortunately some claims have been ...

  • Distributed Measurements Unlock the Future of Design

    The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...

  • Should Your Sensor Have A Connector Or Pin Terminals?

    When it comes to measuring the activity of your project, it’s nice to have options. High precision sensors can offer plenty of selections from the range of your measurements to the output of your readings, but a sensor is only as good at its connection. Connectors and pin terminals are common and dependable connections that relay your readings from within the sensor to the screen in front ...

  • The vibration monitoring evolution

    A recent report from Markets & Markets estimated that demand for vibration monitoring systems will reach nearly $1.5 billion by 2020. That’s a staggering increase of around 50% compared with today – with a compound annual growth rate (CAGR) of more than 6.5%. Is this growth a big surprise though? As a company that has seen first hand the rapid evolution of the ...

  • 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 ...

  • Maintenance tips for cooling towers - White Paper

    Cooling towers are prone to the typical causes of rotating machine failure such as misalignment, but also face a range of specific environmental challenges, including high or gusting wind speeds, dust, sand and, in coastal locations, high concentrations of salt. In the 1990s, for example, vibration and accelerated wear caused a fan blade to shear off a cooling tower in Pennsylvania, ...

  • Airbus Helicopters: Monitoring gearboxes with HUMS accelerometers case study

    Airbus Helicopters needed highly robust, flight-certified accelerometers for permanent monitoring of gearboxes to be quickly designed and delivered. Challenge For helicopters, one of the most dangerous possible scenarios – worse than engine failure – is gearbox failure. Quality vibration monitoring is needed to ensure gearbox health and predict failures, while absolute ...

  • An Inertial Measurement Unit Application for a GPR Tracking and Positioning

    Abstract Abilities of an inertial measurement unit (IMU) for ground penetrating radar (GPR) tracking and positioning are presented at this paper. The IMU operation principle is based on calculating of the device's orientation in space via measurement of linear accelerations and angular velocities. Features of the IMU, GPS and wheel odometer are compared. Principal scheme of the IMU consisted ...

  • Construction and Civil Infrastructures Monitoring Systems

    Civil infrastructures are usually monitored through its whole life cycle. SHM (Structural Health Monitoring) technologies enable the estimation of the structural state and detection of structural change that affects the performance of a structure. Two discriminating factors in SHM are the time-scale of the change (how quickly the state changes) and the severity of the change. These factors ...

  • Crack identification in a cantilever beam using rotational laser vibrometer–based coupled of bending, axial and torsional vibrations

    In this paper, coupled response measurements are suggested for detection of a transverse surface crack in a cantilever beam. The crack has been modelled by a local compliance matrix of six degrees of freedom and simulated for detection. The eigenfrequencies are obtained using finite element method (FEM) and are compared with those of experiments. However, the small changes in eigenfrequencies are ...
