Magnetostrictive Torque Sensors and Materials
IEEE Translation Journal on Magnetics in Japan, 1992Shaft torque sensors based on the magnetostriction effect and magnetostrictive materials used in such sensors are reviewed. Torque sensors employing amorphous ribbons in a chevron pattern and with solenoidal pickup coils have been developed for highly sensitive torque measurements in an intermediate dynamic range.

A force and torque tensegrity sensor
Sensors and Actuators A: Physical, 2004Tensegrity structures represent a special class of flexible structures, whose members can simultaneously perform the functions of strength, sensing, actuating, and feedback control. In this article we show how these structures intrinsic properties can be exploited to construct a smart sensor for simultaneous measurement of six different quantities ...

Development Of An Optical Torque Sensor And Examining Torque-Vibration Correspondence
Journal of Namibian Studies : History Politics Culture, 2023A reliable, non-intrusive, and precise measurement of torque is essential for the dynamic performance and monitoring of rotating mechanical systems. This study helps in presenting a technique for the torque measurement that consists of two different shafts mounted on tapes of zebra and sensors that are optical on the rigid support.

Magnetic differential torque sensor
IEEE Transactions on Magnetics, 1995A new torque sensor structure is presented. The basic idea is a simple torque sensor with a variable magnetic circuit excited by an axially magnetized permanent magnet ring. The circuit is constituted by iron toothed rings, whose teeth relative position changes whenever an applied torque twists the rotating shaft. A Hall probe measures the induction in

A Rate of Change of Torque Sensor
IEEE Transactions on Magnetics, 2007A sensor having an output signal indicative of the time rate of change (ROC) of torque is described. Operating on the same magnetoelastic principles as polarized band torque transducers except for the replacement of field intensity sensors with flux linking multiturn coils, ROC sensors respond exclusively to the variational components of the torque ...

The SI (Systeme International) unit of measurement for force F is the „Newton“ (N), which is one of the 7 base units of that system. In practice, large forces are usually expressed in kN (kilonewton) or MN (meganewton) while for small forces, the mN (millinewton) is used.

Modelling of a micromachined torque sensor
Sensors and Actuators A: Physical, 1995Abstract A micromachined torque sensor head is presented. The torque is evaluated by using an amorphous ribbon fixed on a shaft and an NiFe yoke with exciting coils and CMOS MAGFETs underneath the pole pieces to detect the change in magnetic flux density caused by a torque applied to the shaft.

Magnetostrictive Type Torque Sensor
SAE Technical Paper Series, 1991<div class="htmlview paragraph">A highly sensitive, non-contact torque sensor was developed using amorphous magnetic alloy. A thin strip of amorphous magnetic alloy was bonded onto the surface of the shaft, formed into a chevron shape, then the torque applied to the shaft was detected from the difference in the inductance of the detection coil ...

Optical Torque Sensor Development
2010The purpose of this study is to develop a contactless torque sensor in the mNm range. The applied optical method is based on the birefringe effect of photoelastic materials. The novelty of the modified reflective photoelastic method is the application of a photoelastic tube as a coupling and measuring element between shafts.

On the use of torque sensors in a space robotics application
2005 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005Torque sensors in robotics are used in those applications where high precision positioning of the end effector is required. Technological difficulties often arise in the mechanical design as well as in the placement of the sensor. However, the use itself of the torque sensor for feedback control, in all those cases where elasticity of the transmission ...
