  • Engineers torque technology to medics

    Medical experts and sports scientists are becoming increasingly reliant on engineers as their disciplines become more and more technical. Mark Ingham looks at some of the projects his company, Sensor Technology, has helped behind the scenes. Like most rugby players I took my knees for granted until the day a twisting fall resulted in a torn anterior cruciate ligament. Fortunately these days it ...

  • Torque about improving handling accuracy

    Dry bulk handling is en route to becoming a precision science with a level of control previously undreamt of, thanks to 20 years of research and development into digital non-contact torque monitoring. Dry bulk handling is following many other industrial processes that have been redeveloped from a ‘black art’ to a highly accurate and controlled procedure. A generation ago much of industry was in ...

  • Dynamic rotary torque measurement using surface acoustic waves

    The subject of torque measurement has previously been addressed extensively. Most of the existing transducers either rely on low voltage analogue systems (e.g. conventional resistive strain gauge) or complicated mechanical assemblies by physically assessing displacement, i.e. optical systems. This paper identifies a new, potentially low cost, non-contact, frequency domain strain torque sensor1 ...

  • Providing the Key to Learning

    The electrical machines laboratory at the Dublin Institute of Technology (DIT) has greatly increased in its effectiveness as a teaching resource since TorqSense non-contact torque sensors from Sensor Technology have been fitted to five machine sets. The new sensors replace an existing system of machine monitoring that had proved inaccurate. ...

  • Application notes - viscosity measurement

    Most laboratory viscometers employ the well-known principle of rotational viscometers to measure viscosity by sensing the torque required to rotate a spindle at a constant speed while it is immersed in the sample fluid. This is because the torque, generally measured using the reaction torque on the motor, is proportional to the viscous drag on the immersed spindle and thus the viscosity of the ...

  • Improved Performance of Motor Drive Systems

    The paper describes the application of a non-contact, high bandwidth, low cost, SAW-based torque measuring system for improving the dynamic performance of industrial process motor-drive systems. Background to the SAW technology and its motor integration is discussed and a resonance ratio control (RRC) technique for the coordinated motion control of multi-inertia mechanical systems, based on the ...

  • A blind estimation of speed and rotor position of permanent magnet synchronous motor from the measurements of stator currents using extended Kalman filter

    A number of techniques have been developed for estimation of speed or rotor position in motor drives. In this paper, an extended Kalman filter (EKF) is developed for the estimation of speed and rotor position using only the measurements of three phase stator currents. Conventional mechanical sensors are not needed for this estimation. The paper proposes the modelling of the dynamic equations of ...

  • Pay as you sense

    Equipment rentals are increasingly helping companies overcome the hurdle of finding investment capital to fund development and verification projects. The current phase of the economic cycle, recovery from a slowdown, is always difficult and frustrating, as Mark Ingham of Sensor Technology identifies: "Companies are seeing their markets improve, but don't have the reserves to finance all the ...

  • Mephisto 3D scanner used in medical foot scanning

    This paper juxtaposes simple yet sufficiently general robotic mechanisms for ankle function evaluation, measurementand physiotherapy. For the choice, design and operation of the mechanism, a kinematics model of foot is adopted frombiomechanics, based on the hypothesis that foot kinematics are similar to a 2R serial robot. We undertake experiments,using a 3D scanner and an inertial sensor in order ...

  • Accuracy and Cost Savings from Automatic Optimization of Dewatering

    Improvements in sensor and automation technology in recent years have made it possible to design a system to control the key variable parameters in and around the dewatering process. By continuously analyzing feed conditions and output from the process, an automated optimization system can make necessary proactive adjustments to the internal settings of the dewatering equipment, the polymer ...

  • In Situ Rheological Monitoring of Viscous Non-Newtonian Fluids using a Helical Ribbon Agitator

    Mechanically degraded food fluids were modelled as Power law fluids in a pilot scale (42 l) helical ribbon agitation vessel. Effective rheological representative flow curves determined from speed/torque data proved comparable to off-line laboratory rheometer measured data. Modelling effective viscosity as a Power law function gave effective consistency coefficient Keff which correlated strongly ...

  • Technology transfer is more important than innovation

    Innovation, we are told, is the key to a successful manufacturing economy. Invent and patent something and you will make money on every one made - if it is mass produced you get an on-going income. Tony Ingham of Sensor Technology Ltd looks at his experience over two decades and tries to draw some general principles that may help Britain in its new ambition to rebuild the manufacturing base. We ...

  • Tank terminal demonstrates the electrically operated solution for ESD Valves - case study

    Overview Since the disastrous fire at the Buncefield fuel depot in 2005, much has been done to ensure that such a catastrophic accident should not happen again. Led by COMAH (Competent Authority/Industry Standards Task Group), safeguards have been put in place by the petroleum industry to provide additional safety and environmental protection to tank storage installations. Endorsing the ...

  • Waste to energy – processing waste with a high thermal value to substitute combustibles

    With the taking effect of the TASi (Technical Regulations on Estate Waste) in 2005, non-treated waste must no longer be disposed of and deposited. Commercial and industrial residues with a high thermal value such as rejects from paper industry, punchings from rubber and plastics, and other mono-fractions which are characterized by homogeneity and constant combustible properties through mechanical ...


  • Mobility is key in landclearing effort theft of grinder from jobsite leads to change in approach to processing.

    One of the oldest adages around says that everything happens for a reason. And although it is hard to accept at the time, an unfortunate event can often turn out to be the proverbial blessing in disguise. Such apparently has been the case for Sunshine Land Design, which, since the theft of one of its main pieces of grinding equipment, has moved to a track-mounted horizontal grinder, dramatically ...

  • Steam Heater Pulp Stock Heating Paper Mill

    After upgrading its bleach plant in 1987 to accommodate a two-stage elemental chlorine-free (ECF) bleach sequence, Cross Pointe Paper (now Flambeau River Papers LLC), Flambeau mill in Park Falls, Wis. subsequently added a totally chlorinefree (TCF) sequence in response to market demand. The TCF sequence, however, required heating, rather than cooling, of the mill's mediumconsistency stock during ...
