Combined magnetoelastic transducer for torque and force measurement

IEEE Transactions on Instrumentation and Measurement, 1997
The paper presents a new type of combined magnetoelastic force and torque measuring transducer. The magnetoelastic principle of operation has been used due to the mechanical simplicity of such a transducer. The shape of magnetic core and the configuration of exciting and sensing windings have been chosen to minimize the cross-sensitivity between force ...

Miniaturized magnetoelastic torque transducers

IEEE Transactions on Magnetics, 1999
Torque 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, 1971
The 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,

Torque standard machine for calibration of reference torque wrench and torque transducer at Nim

Tenth International Symposium on Precision Engineering Measurements and Instrumentation, 2019
The paper describes a new torque standard machine at NIM. The new reference torque standard machine is designed to calibrate the reference torque wrench and torque transducer. The relative expanded uncertainty of this torque standard from 10Nm to 5000Nm is better than 5×10-4（k=2）.

“Negative” Hysteresis in Magnetoelastic Torque Transducers

IEEE Transactions on Magnetics, 2009
Unusual 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 ...

A transducer for measurement of finger joint torques

Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002
A device for measuring torques generated about the joints of the fingers has been developed. The design utilizes a parallelogram construction that allows the device to fit different sizes of hands. The device has the capability to measure isometric moments generated about the MP, PIP and DIP joints of a single digit.

New Optical Torque Transducer and Dynamometer

IEEE Transactions on Industrial Electronics and Control Instrumentation, 1970
Most 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.

A rotational rheometer with a drag‐cup torque transducer

Journal of Polymer Science: Polymer Physics Edition, 1975
AbstractA rotational cone‐and‐plate rheometer incorporating a drag‐cup torque transducer and a frictionless, wire suspension has been designed and constructed. The instrument design provides for a controlled atmosphere for the sample, including anhydrous conditions necessary for studies on solutions of polymers in strong acids.
