  • Patent number: 6260421
    Abstract: Method and device for increasing the accuracy when performing measurements with a torque sensor (1, 2) in engines, which is mounted substantially concentrically in connection to a rotatable shaft (12), where said torque sensor (1, 2) is constituted by at least one coil (20, 22), and at least one zone (30) which is provided with parallel lines of a suitable conductive material such as copper. The coil (20, 22) is provided with connections for measuring the voltage, whereby the rotatable shaft (12) has a recess (50, 52). The zone (30) is either placed on the inner envelope surface of the recess (52) where said zone (30) encloses a stationary coil (22) which is journalled in the recess (52), or on an outer envelope surface of a measuring shaft (10) attached in the recess (50), which is enclosed by a stationary coil (20).
