摘要： The invention relates to a device for non-contact measuring of stresses in a bar-shaped body (1), e.g. a cylindrical bar, shaft or the like. In at least one transverse zone (2, 3) the bar (1) is provided with a number of thin strips (4) of an amorphous magnetoelastic material, distributed along the circumference of the zone, said strips (4) being affixed to the circumferential surface of the zone and extending at a pitch angle therealong, preferably at a pitch angle of 45 DEG . Means (5) are provided for generating a magnetic field over said zone (2, 3) and a pick up coil (6-13) encircling the bar is provided for each zone (2, 3), said pick up coil being connected to a measuring unit (16, 16A) for indicating signals generated in the coil. According to the invention each pick up coil (6-13) encircling the bar (1), which is associated with a strip zone (2, 3), is oriented in relation to the bar (1) in such a manner that the magnetosensitive axis of the pick up coil includes an acute angle, preferably an angle of 45 DEG , with the axis of the bar (1) in the strip zone.

摘要： The apparatus of the invention is a water level probe (10) comprised of a probe body (24), a sleeve (28) having openings (56) and (58) permitting fluid flow and encasing part of a magnetostrictive sensor (52), and an external housing (26) encasing electronic circuitry (40) and (42) for processing and transmitting the electric signal generated by the magnetostrictive sensor and sealing the circuitry from fluids. The sensor comprises a float (54) slidably mounted on a rod (50), the mass of the float being adjusted to float in water (16) but sink in a petroleum product (14), thereby ensuring that it will float at the interface between the water and the product. The water level probe is used in the method of the invention to measure the depth of the water in a vessel (12) storing hydrocarbon product at predetermined time intervals. The longitudinal angle of inclination ((Theta)) of the vessel with respect of the horizon having previously been determined, the volume of water in the vessel is calculated from the depth measurements. The rate of hydrocarbon leakage is then determined from the calculated volumes to ascertain the rate of change of water volume over time.

摘要： A method and apparatus for comparing torsional stress/strain states of a power transmitting member of an internal combustion engine to detect an abnormal combustion condition, including misfire, knock or roughness. Statistical processing steps may be used to detect an abnormal combustion event including: calculating a mean and standard deviation for a set of signals related to the torsional stress induced in the power transmitting member, calculating a difference between a later signal and the mean, calculating a ratio of the difference to the standard deviation, and comparing the ratio to a threshold. The ratio so obtained from a given cylinder may further be compared with one or more other such ratios from other cylinders. In other words, the autocorrelation and/or cross-correlation techniques may be used. A magnetostrictive sensor may preferably be used to obtain the signals relating to the torsional stress in the power transmitting member, such as the engine crankshaft. In addition, the magnetostrictive sensor may include windings to cancel induced electromagnetic interference signals. The magnetostrictive sensor may also generate signals relating to the position of the power transmitting member in addition to the torsional stress in the power transmitting member. Spatial integration techniques may be used to obtain torsional stress/strain signals which are independent of the rotational speed of the power transmitting member. Spatial interaction may be performed using variable amplifiers, variable attenuators, switched capacitors or other techniques.
