Abstract: A magnetoelastic transducer for measuring stresses is formed of a disc-shaped core of magnetostrictive material provided with four channels perpendicular to the plane of the disc and arranged at the corners of a square figure. It is placed in a circular opening of the object to be tested. Stresses are transmitted to the disc from the object through four transmission elements situated equidistant from each other and symmetrically arranged in relation to the diagonals of the square.

Abstract: A sealing cone adapted to be secured on an indicating tap of a diesel engine has a central passage communicating with a diaphragm mounted in a housing. Another housing includes a forcemeasuring device such as a transducer. Pressure forces are transmitted from the diaphragm to the transducer by a central cylinder, and counter-acting tensile forces by a ring surrounding the cylinder and connected by sets of low-heat-conducting screws to both housings, the screws of the two sets being symmetrically spaced from each other around the ring. The cylinder and ring are formed of rigid thermally insulating material. The transducer is thus protected from the heat of the diesel engine.

Abstract: An annular magnetoelastic transducer has a core in the shape of a cylindrical ring. The core is manufactured by winding a striplike magnetostrictive material so that the plane of the strip is parallel to the central axis of the ring. In the core is a number of holes which are arranged substantially radially through the core. The holes are arranged in groups which are evenly distributed around the circumference of the core. In the holes there is a winding connected to a current source for generating a magnetic flux in the core and a winding connected to a measuring device for indicating the alterations of the magnetic flux which appears when the core is subjected to mechanical forces.
