A method for preventing magneto-elastic torque transducers (1,2) from being influenced by a static, axially-extending magnetic field (9) comprises dividing the driving shaft between the driving source and the load in such a way that the shaft (3) between the driving source and the transducer shaft and the shaft (4) between the transducer shaft and the load, respectively, are provided with a shaft part (7,8) of non-magnetic material and that the transducer and the transducer shaft including the non-magnetic shaft parts are surrounded by an external magnetic shield (5) provided with flanges such that a very small air gap is present between the shield and the non-magnetic shaft parts. |
