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 ...

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）.

Analysis of a non-contact magnetoelastic torque transducer
Journal of Magnetism and Magnetic Materials, 2008Results are presented for the performance of a magnetoelastic torque transducer that converts a torque-induced strain in a nonmagnetic shaft into changes in a measurable magnetic field. The magnetic field is generated by a thin magnetostrictive layer that is coated onto the circumference of the shaft. The layer is magnetized and has an initial residual

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 ...

A torque transducer utilizing two oppositely polarized rings
IEEE Transactions on Magnetics, 1994The use of two contiguous rings having oppositely directed circular magnetizations is shown to effectively eliminate the ambiguous effect of ambient axial magnetic fields on the indication of torque as found with single ring transducers. An experimental two ring transducer showed less than 1% of the field sensitivity of a same overall size single ring ...

A torque transducer utilizing a circularly polarized ring
1992. Digests of Intermag. International Magnetics Conference, 1992A novel type of magnetoelastic torque transducer is described. It consists of two elements: a circumferentially magnetized magnetostrictive ring, rigidly attached to a shaft carrying the torque to be measured, and a Hall effect or similar magnetic field intensity sensor mounted in proximity to the ring.
