Magnetoelastic torque transducer (1,2) shielded from the influence of static of quasi-static magnetic fields (9) with a driving shaft (1) between the driving source (3) and the load (4) being divided 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 (10,11) such that a very small air gap exists between the flanges and the non-magnetic shaft parts (Fig. 2). |
