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.

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,

Torque standard machine for calibration of reference torque wrench and torque transducer at Nim
Tenth International Symposium on Precision Engineering Measurements and Instrumentation, 2019The 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, 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 ...

A transducer for measurement of finger joint torques
Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002A 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.

Magnetoelastic torque transducer nondestructive to the measured shaft
SPIE Proceedings, 1998This paper describes a magnetoelastic torque transducer nondestructive to the measured shaft. A sensing sleeve added to the measured shaft can not only measure the torque of the rotating shaft, but also be nondestructive to the shaft. Moreover, the grid areas are cut on the sleeve, which enables the common coil structure to replace the classic ...

Torque transducer based on fiber Bragg grating
SPIE Proceedings, 2016In order to obtain the accurate torque measurements in harsh condition, such as marine environment, a torque transducer based on fiber Bragg grating is proposed in this paper. According to its optimized elastomer design and fiber Bragg grati ng patching tactics, the new proposed torque transducer realizes automatic compensations of temperature and ...

A rotational rheometer with a drag‐cup torque transducer
Journal of Polymer Science: Polymer Physics Edition, 1975AbstractA 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.
