An optical torque transducer for high-speed cutting
Measurement Science and Technology, 2006In this paper, the design and manufacture of an angular twist-type optical torque transducer is described. It is based on the measurement of the angular twist of a stainless steel wire gauge proportional to the torque transmitted, through two optical reflective sensors.

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.

The influence of temperature and humidity on the sensitivity of torque transducers
Measurement, 2016Abstract This paper presents a study of the effect of temperature and relative humidity on the sensitivity and the characteristics of torque transducers such as residual zero torque, reversibility and creep. Temperature and humidity coefficients of the sensitivity take positive as well as negative values.

A Quantitative Theory of Magnetic Anisotropy Torque Transducers
IEEE Transactions on Instrumentation and Measurement, 1965A companion paper [1] has given a historical review of torque transducers using the phenomena of magnetic-stress anisotropy and has described the design and operating principles which will yield devices of high precision. The present paper describes a physical theory of operation which yields quantitative results in reasonable accord with the measured ...

Optical transducer in torque measurement
In industry, when a robot is used in assembling two parts connected by a threaded fastener, measuring and controlling the torque applied to the fastener become very important. Torque sensors are used to commonly perform this task. Torque sensors can be divided into two types: contact torque sensors and non-contact torque sensors.openaire +2 more sources
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 ...

Measurement uncertainty of torque measurements with rotating torque transducers in power test stands
Measurement, 2007Abstract The objective of the presented study is to introduce a method for estimating the measurement uncertainty of torque measurements. Unlike the well-known approaches, the uncertainty shall take into account the effects acting during torque measurement in industrial applications like power test stands. These effects include the effects also known

DEVICE FOR AT LEAST TRANSDUCING AND/OR TRANSMITTING TORQUE
2004Disclosed is a first device for at least transducing or transmitting torque, comprising a shaft which is mounted inside a housing of the first device via at least one bearing. A second device can be releasably connected to the shaft. The housing and the shaft are connected to each other in an electrically conductive manner via another component, at ...
