  • 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 ...

  • A Device for the Measurement of Sub-Surface Ground Vibrations

    A reliable measurement of free-field stress waves from transient loading has several important applications, for example, in the design of effective wave barriers to protect sensitive equipment and in the design of underground protective structures against explosive loading, to name a few. The characteristics of a stress wave are highly dependent on the energy source and the soil medium through ...

  • Finite element modelling and vibration control of a tetrahedral space frame applied to micromachining

    This paper presents the modelling and vibration control of the tetrahedral space frame. The tetrahedral frame is a structure that is used in precision machining applications. When machining at a high precision requirement, structural vibration is of the utmost concern. This research develops finite element models using ANSYS and Matlab that can be used to implement a positive position feedback ...

  • Brüel & Kjær’s vibration check systems validated and certified by Turbomeca

    Since 2002, Brüel & Kjær has been working very closely with Turbomeca to develop dedicated Vibration Check systems for helicopter engines, measured on the aircraft on the ground during engine run-up. This has resulted in a range of standard systems that can be used for measurements on virtually all Turbomeca engines used on helicopters. Turbomeca has issued Service Letters to ...

  • Controlling combustion noise in direct injection diesel engine through mechanical vibration measurement

    The next generations of direct injection diesel engines have greatly improved their performances compared with petrol engines. However, one of the pending subjects is the noise and vibration levels, due to working cycle itself. The design effort to reduce the emissions of noise and vibration transmitted to the vehicle's driver could be lessened because of the assembly process variation. In this ...

  • 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 future is condition monitoring

    It’s been a big month here at Hansford Sensors. We kicked off November by celebrating our 10thanniversary, during which time we were playfully predicting what our company may look like in another decade. While our thoughts on this are strictly hypothetical at this stage, thanks to the release of a new report we now have a better idea of the state of the condition monitoring ...

  • 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, ...

  • Controlling the timing chain noise in diesel engines

    Timing drive by chain is commonly used in passenger cars especially in diesel engines with double overhead camshafts owing to their numerous advantages compared with belt drive systems. However, one of the important subjects to take into account is the timing chain noise, so-called "meshing noise" that can be perceived by the driver. The manufacturer's efforts to reduce it, are focused ...
