CA 2674054

A method and device for measuring a property, such as torque, includes a plurality of sensors, and a measuring device. The sensors attach to a downhole apparatus at a distance from one another. The sensors provide signals indicating their positions. A logic circuit may calculate an angle between the sensors. The logic circuit then calculates the property based on the angle, the distance between the sensors, and other known physical properties of the downhole apparatus.

L'invention concerne un procédé et un dispositif destinés à mesurer une propriété, telle que le couple, au moyen d'une pluralité de capteurs et d'un dispositif de mesure. Les capteurs se fixent à un appareil de fond à une distance donnée les uns des autres. Lesdits capteurs fournissent des signaux indiquant leur position. Un circuit logique peut calculer un angle entre les capteurs. Ce circuit logique calcule ensuite la propriété sur la base de l'angle, de la distance entre les capteurs et d'autres propriétés physiques connues de l'appareil de fond.
