摘要： A stainless steel load cell (42) having a shear web (58) design suitable for use in a continuous casting environment is disclosed. Strain gauges (64) are disposed on both sides of each of the four webs (58) to detect deformation, while a wheatstone bridge (69) is provided, having thermally-compensated potentiometers (72), to balance the strain gauge output to provide a signal indicative of an applied load. The interior of the load cell is sealed on both sides with disc shaped stainless steel seal members (84). The interior of the load cell is coated with a very low durometer polymer (86) to provide the bridge (69) and strain gauges (64) with a barrier to moisture and other corrosive vapors. The load cell is enclosed by an air-tight canister that is supplied with pressurized nitrogen gas for drying purposes.

摘要： n extensometer having two spaced-apart mounting bases adapted to be mounted on a load-bearing structure with its axis of sensitivity intersecting the axis along which load-induced strains are generated at 45°. The extensometer includes a pair of parallel links connecting the mounting bases through respective flexure hinges. In one embodiment, one of the links is also connected to one of the bases through an intermediate flexure hinge so that the link deforms responsive to relative movement applied between the bases along the axis of sensitivity. A strain gauge mounted on this link measures the magnitude of the deformation. In a second embodiment, a strain-instrumented measurement beam extends between the two links so that it deforms responsive to pivotal movement of the links as the mounting bases move in opposite directions along the axis of sensitivity. This embodiment of extensometer may be mounted on the load-bearing structure through three or more mounting points. In order to facilitate mounting of the extensometer on a structure without pre-straining the extensometer, a rigid plate may be connected to the extensometer through a plurality of pins, each of which extends from the plate through the extensometer at each of the mounting points. The pins terminate in a point and they are biased against the structure by a threaded fastener extending from the plate, through the extensometer, and into the structure.

摘要： The invention concerns a load-sensing device of the kind comprising a resiliently flexible member (2) and an arm (13), an end portion of which is rigidly connected to the flexible member whereas its opposite end portion is free. The distance between the free end portion of the arm and the flexible member is changeable in response to load exerting on the flexible member and to the resulting flexible deformation thereof. The flexible member (2) has a tubular cross-sectional shape with an interior cavity (12) in which the arm (13) is disposed. In the area of the free end portion of the arm a transducer (17) is located to sense the distance from the arm to the flexible member and/or a switch (15) which, in response to the mutual relative movement between the flexible member and the free end of the arm, may be shifted between an open and a closed position and which is arranged to close or open a signalling circuit upon attainment of a load of a predetermined value.

摘要： A load cell for transmitting a signal depending on the force exerted thereon has an elastic element in the form of a rubber sleeve (11), which is in contact with a pressure transducer (14) and is enclosed in an annular compartment formed by an annular recess in a housing (2) and a corresponding recess in a rod (6), that is exposed to the force and extends into the housing. A ring (10, 12) is arranged at each end of the rubber sleeve to transmit forces in the two axial directions of the rod to the sleeve from the respective end shoulders (2', 3', 8', 9') of the recesses.

摘要： In surface force apparatus and in atomic force microscopes, a free surface and an atomically sharp tip, respectively, are mounted on a cantilevered weak spring within the instrument. The present invention provides a substitute for the weak spring, in the form of a piezoelectric bimorph (10) comprising two elongate slabs of piezoelectric material, held in intimate contact at one end by a clamp (12). The bimorph is also clamped at a second location by a second clamp (14), preferably slideable on the bimorph. The second clamp is adapted to carry a supporting adaptor (15) for a free surface (20) or an atomically sharp tip. Measurement of charge developed on the bimorph due to its flexure under an applied force enables the value of the applied force to be calculated.

摘要： A mechanical transducer comprises a converter which comprises a plurality of elongate flexible elements (1) joined together at their opposite ends and spaced at intervals around a longitudinal axis of the transducer. The opposite ends (2, 2) of the converter are displaceable towards and away from each other along the axis, which displacement is accompanied by a bowing or straightening of the elongate elements (1). Thus, an axial force applied to the converter will be converted to a radial force exerted by the elongate elements (1), or a radial force applied to the elongate elements (1) will be converted to an axial force.
