Abstract
A magnetoelastic torque sensor () has an emission coil () for generating a magnetic field in an object (), the torque of which is to be determined. The emission coil is axially oriented (A) and has an axial emission coil end surface () which can be guided towards the object (). At least two reception coils () at a distance from the emission coil and having, respectively, a receiving coil end surface () which can be guided towards the object () to capture a response signal induced in the object () by the magnetic field of the emission coil (). At least the receiver coil end surface () of one of the receiver coils protrudes beyond the emission coil end surface () to a selected distance from the object ().
