Miniaturized magnetoelastic torque transducers
IEEE Transactions on Magnetics, 1999Torque transducers based on circumferentially polarized band technology are shown to be scalable downward to accommodate torque measurements to at least low mN/spl middot/m ranges. Shaft diameter for any required torque range is determined by material strength, while band width and separation are selected primarily to meet specific field detector ...

Dynamic micro-torque transducer
Experimental Mechanics, 1971The desing and characteristics of a torque transducer developed to measure sinusoidally oscillating torques from 10−6 lb-in. to 1.0 lb-in. and from near static to 500 Hertz are discussed. The transducer was used to transmit, as well as measure, the driving-point torque to a 0.5-in. diam circular cylinder of low-modulus test material whose viscoelastic,

Increased torque transducer sensitivity via oversampling
Rheologica Acta, 2001The sensitivity of a commercial torque transducer under oscillatory shear conditions is extended by about a factor 3–5 into the small torque region. This increased sensitivity is a result of a straightforward data treatment in the time domain termed “on the fly oversampling”. This method is enabled by the emergence of modern ADC-cards.

A Digital Torque Angle Transducer
IEEE Transactions on Industrial Electronics, 1984This paper describes a digital transducer which displays the torque angle of a synchronous machine operating in motoring or generating modes. The transducer can also provide a torque angle feedback signal for digital control applications in power systems.

Optical fibre Bragg sensor torque transducer
SPIE Proceedings, 2007The benefits of an Optical Torque Transducer (OTT) based on optical fibre Bragg sensors for applications in any environment prone to electro-magnetic and temperature influences are outlined. By using an optical Rotation Coupler (RC) the transducer avoids slip rings or telemetry systems.

“Negative” Hysteresis in Magnetoelastic Torque Transducers
IEEE Transactions on Magnetics, 2009Unusual manifestations of magnetomechanical hysteresis often observed in magnetoelastic torque transducers are described. Characterized by a remanent field at zero torque having a polarity opposite to that at the torque peak, this "negative" hysteretic effect is shown to be of magnetic origin and hypothesized to reflect axial magnetization of ...

New Optical Torque Transducer and Dynamometer
IEEE Transactions on Industrial Electronics and Control Instrumentation, 1970Most torque measuring transducers develop an electrical output signal proportional to the twisting of an accurately machined and calibrated seciton of shaft known as a torque bar, Fig. 1.
