摘要： A magnetoelastic torque transducer for measuring, in a non-contacting manner, the torque in a stationary or a rotating shaft. The transducer comprises a shaft (1) with surrounding excitation windings (2, 3) and measuring windings (10, 11). Concentrically with the windings, anisotropic measuring zones are created by applying layers (8, 9), for example in the form of copper strips, on the surface of the shaft. The angle between the strips and a generatrix to the cylinder surface of the transducer shaft is in a preferred embodiment chosen to be .+-.45.degree. (FIG. 5).

摘要： A torque transducer for measuring torque transmitted in a rotating as well as a stationary shaft. The torque transducer comprises a transducer shaft 1 arranged with a cylinder-shaped magnetoelastic region 2 fixed to the cylindrical periphery of the transducer shaft, which cylinder-shaped magnetoelastic region is permanently magnetized in the azimuthal direction. The transducer shaft with the cylinder-shaped magnetoelastic region is surrounded by a winding 4 which is supplied by an alternating current. Further, the winding is connected to a phase-sensitive detector 5. According to the present invention, a magnetic and non-linear ferromagnetic material 3′ is arranged in physical contact with the cylinder-shaped magnetoelastic region 2. The advantages are that the transducer shaft is manufactured independently of the magnetic properties of the shaft material and may substantially consist of a ferromagnetic material.

摘要： A magnetoelastic torque transducer comprises a shaft, three stationary coils connected in series to magnetize the shaft and three coils to sense moment transmitted in the shaft, and a magnetic casing surrounding the coils. The shaft has three parallel annular zones provided with such anisotropy that the magnetic field in the shaft is deflected by an angle .alpha. relative to a generatrix to the shaft in the outer zones and is deflected by an angle .alpha. to a generatrix to the shaft in the middle zone, the axial extension of both outer zones being substantially half that of the intermediate zone. The angle .alpha. should be at least 45.degree. in order to obtain good sensitivity in the transducer. The excitation coils are arranged concentrically to the shaft, each being located outside an annular zone and the outer excitation coils being wound with substantially half as many turns as the central excitation coil. Concentric with each excitation coil is a measuring coil, the outer measuring coils being wound with substantially half as many turns as the central measuring coil and this being arranged to be inverse-connected to the outer measuring coils.

摘要： To reduce hysteresis effects on the output of a magnetoelastic torque transducer subjected to possible overloads, the transducer is constructed with a measuring sleeve which is rigidly attached by its ends to a surrounded measuring axle. A yielding region in which the material of the sleeve deforms plastically relative to the axle in case of an overload is provided between the measuring zones where the magnetoelastic stresses in the measuring sleeve are sensed. A ring of holes can provide a suitable yielding region.

摘要： A method and a system for phase sensitive rectification of signals from transducers driven by an AC excitation signal will be disclosed. The method and system demand a very moderate calculation capacity, thereby to facilitate the use of low cost microprocessors of ordinary speed. The present method and system utilize a sampling being synchronized with the transducer excitation frequency f. Sampling of the sensor signal is performed by an A/D-converter at a high sampling frequency, nf. The sampled signal then is averaged over half a period of the excitation signal frequency, whereby the starting point of the averaging is decided by the time of commutation. This is equal to filtering the sampled signal by a decimating filter. The rectification may then may be preformed with a number sequence sampled by the optimal sampling frequency 2f (twice the excitation frequency only) instead of the sampling frequency nf used for obtaining high resolution. The output then is further filtered by means of a digital filter acting as an ideal low-pass filter as well as an output filter for achieving a desired output signal level. The signal output will be then be simply made available for further digital processing. However, the output still offers high resolution measurements in spite of only demanding moderate speed microprocessor capacity for the processing.

摘要： A magnetoelastic force transducer comprising two identical, cylindrical bodies defining a hollow magnetic core and held together by means of a force-transmitting stud bolt has its measuring and excitation windings located in the core. The interior of the core is constructed such that a thin cylindrical tubular wall is formed opposite to a respective measuring winding in each one of the bodies, whereby when the core is force-loaded via the stud bolt a compressive stress arises in one of these tubular walls and a tensile stress arises in the other. To eliminate a possible measurement signal at zero applied force a magnetically asymmetric center pole in the form of a punched disk of a soft-magnetic material and having the same diameter as the core and having a foil of a similar material secured on one side is located between the bodies. The hickness of the foil determines the magnitude of the signal adjustment.

摘要： A dimension-gauging system to determine at least one dimension of a non-ferrous, electrically conducting object produces a magnetic field inside the object and changes the excitation of the magnetic field. A signal processing unit measures the reaction of the magnetic field to the change in excitation, obtains an actual field transfer function between the excitation and the measured field reaction and determines the at least one dimension of the object by fitting the measured field transfer function to a predetermined field transfer function, where the predetermined field transfer function represents the dynamic behavior between the excitation and the measured field reaction with the one dimension as a parameter.

摘要： A method for detection of misfiring of an internal combustion engine, wherein the torque of the internal combustion engine is measured with the aid of a torque sensor mounted on the crankshaft of the internal combustion engine and wherein a torque signal is sampled speed-synchronously with the aid of a sensor. A digital filtering of the torque signal is carried out with a digital filter with a finite impulse response which blocks or damps a selection of integer or half-integer multiples of the speed of the internal combustion engine. The selection of speed multiples is substantially dependent on the number of cylinders of the internal combustion engine.
