Abstract: A load cell with a Roberval structure having an anti-offset function, and a weighing device are disclosed. The load cell includes strain detection elements mounted on an elastic element which includes a loading portion for receiving a load from a connector, a fixing portion for fixing the elastic element, a strain generation portion for converting the load into deformation, and a parallel guide beam for transferring the load and keeping the loading portion translational when loaded. The strain generation portion includes at least one hollow cavity body. The loading portion and the fixing portion are respectively located on left and right sides of the strain generation portion. The parallel guide beam is located at upper and lower portions of the strain generation portion A center of rotation and a geometric center of the strain generation portion coincide when the load cell with the Roberval structure is loaded.

Abstract: A wall shear sensor includes a floating element fixedly attached to a base. The floating element has a sensing head opposite the base, and a split-beam flexure between the sensing head and the base. The wall shear sensor further includes at least one strain gauge coupled to the split-beam flexure, which measures strain imposed on a portion of the split-beam flexure when a wall shear is applied across a head surface of the sensing head. The split-beam flexure has at least one channel defined through the split-beam flexure parallel to a first transverse axis of the floating element. The floating element sways perpendicular to the first transverse axis of the floating element when a wall shear is applied across the head surface of the sensing head. Wall shear measurement systems include a test body, a sensor housing mounted to the test body, and a wall shear sensor in the sensor housing.

Abstract: A load cell includes a flexural element in which a Roberval mechanism is formed by a pair of top and bottom parallel beams each including two thin sections at a back and a front in a longitudinal direction, which are integrated with a fixed portion and a movable portion, and strain gauges bonded to the thin sections. Strain gauges are bonded to one of the thin sections of pulling side and to one of the thin sections of compressing side, and circular apertures are formed through the remaining two thin sections. The performances of the load cell such as the reduction of the measurement error and of the period of time before the start of the measurement are achieved.

Abstract: Systems and methods are described for monitoring displacement on structural elements of subsea systems such as on components of a subsea pipeline network used to transport production fluid from a subsurface wellhead to surface facilities. The described techniques sense changes in displacement using a sensing blade, for example made of crystalline material such as sapphire, that is anchored to the structural element such that it is approximately perpendicular to the direction of sensed displacement. Displacement is sensed as bending of the sensing blade using one or more instruments fabricated on the blade. Robustness of design is in part provided by additional flexible non-sensing blades mounted in parallel to the sensing blade.

Abstract: A boom protection system prevents damage to an insulated boom section. The boom protection system has a static strain-detection assembly, a pressure-detection assembly, and an alarm. The static strain-detection assembly is configured to determine a load disposed from an implement at a distal end of said insulated boom section. The static strain-detection assembly includes a subject plate presenting a void therein, a traversing member spanning the void, and a strain gauge disposed adjacent to the traversing member. The pressure-detection assembly is configured to detect pressure within a hydraulic cylinder that is associated with the insulated boom section. The pressure detection assembly comprises a first pressure gauge at a distal end of the hydraulic cylinder, and a second pressure gauge at a proximal end of the hydraulic cylinder. The alarm is configured to alert a user of potential structural damage to the insulated boom section.

Abstract: A method for producing a force-measuring element (10) having at least one articulation point (20) which separates one region of the force-measuring element (10) into two connected subregions (11, 12) which can be deflected in relation to one another. The method includes: providing a force-measuring element blank (10), removing material from the force-measuring element blank (10) in order to produce the articulation point (20), checking whether the deflection behavior of the subregions (11, 12) which is produced by the articulation point corresponds to a predefined specification, defining a correction form (30) which can be produced through material removal and compensates for an ascertained deviation from the predefined specification, correcting the articulation point geometry using a laser and the previously defined correction form (30), through material removal at the articulation point.

Abstract: A device includes a first member (120) and a second member (122) disposed in series along a longitudinal axis. The device also includes links coupling first joints (124, 126) of the first member to second joints of the second member (128, 130). The first and second members and the links arranged to define a planar parallelogram linkage. The devices also include a resilient element (142) disposed between the first member and the second member, the first member and the second member preloaded against the resilient element. The first member and the second member are preloaded to provide an arrangement of the first and the second joints in which a motion of the first joints with respect to the second joints is constrained to a direction substantially parallel to the longitudinal axis. The devices further include a sensor (140) for generating a signal indicating a separation between the first member and the second member.

Abstract: A transducer for measuring normal force of a compliant pin includes a fixture having a base. A supporting beam extends from the base. A sensing beam is positioned proximate to the sensing beam and supported at at least one end thereof. The fixture has a slot positioned between the supporting beam and the sensing beam and configured to receive the compliant pin. A strain gauge array is provided on the sensing beam for sensing strain of the sensing beam. The strain of the sensing beam corresponds to normal force imparted on the sensing beam by the compliant pin. The sensing beam is configured to be deformed when the compliant pin is loaded into the slot and the deformation corresponds to strain of the sensing beam configured to be sensed by the strain gauge array.
