    Abstract: The present invention includes an elastic hollow body 2 in which a fluid is filled tightly, a pressure sensor 4 for detecting the pressure of the fluid in the elastic hollow body, and an adapter 6 for coupling the elastic hollow body to an external movable member. The elastic hollow body 2, having a hollow sphere portion 2a having a roughly constant wall thickness, is deformed when an external contact load is applied thereon, to cause a rise in its inner pressure, which is in turn detected by the pressure sensor 4. This provides such effects: (1) that the sensor of the present invention can accurately measure a contact load without being influenced by a possibly changing direction in which a force to be measure is applied; (2) that it can be attached easily and can measure a load immediately after attachment; (3) that it is well resistant against an instantaneous shock load; (4) that it can easily model a substance when it comes in contact therewith; and (5) that it is kept free of deterioration in sensitivity.

    Abstract: A force gage for measuring a tensile force in a pneumatically-operated device, includes a parallelogram linkage having a pair of longitudinal arms in spaced-apart parallel disposition, and a pair of transverse arms in spaced-apart parallel disposition and hingedly interconnecting the longitudinal arms, with a first one of the longitudinal arms being acted upon by a tensile force and movable by the tensile force in the direction of the tensile force, whereby the pair of longitudinal arms is oriented in a direction parallel to the tensile force. A probe is positioned between the transverse arms and securely fixed to a second one of the longitudinal arms for generating a pneumatic pressure signal commensurate with the tensile force. The probe has a casing and a sensing element which projects out of the casing and is acted upon in dependence on the tensile force by a force-applying structure which may be either the first longitudinal arm or one of the transverse arms. In order to permit application of the force gage for hoists of varying load-carrying capability, a first elastic element is connected with at least two of the pair of longitudinal arms and the pair of transverse arms, such that the movement of the first longitudinal arm in response to the tensile force is opposed by an elastic force applied by the first elastic element, and a second elastic element, with the sensing element being connected in series with the second elastic element and supported by the force-applying structure.

    Abstract: A device for detecting deformations in solids includes a casing constructed and arranged to be insertable in a solid. The casing has walls defining a substantially closed container. The container has an inner dividing wall separating the container into an upper enclosed section and a lower enclosed section. A fluid substantially fills the lower enclosed section and is in fluid communication with the interior walls of the lower enclosed section. A first strain-sensing system is in fluid communication with the lower enclosed section of the container such that deformation of the walls causing pressure changes in the fluid are detected by the first strain-sensing system. A second strain-sensing system is disposed in the upper enclosed section. The upper enclosed section is at least partially filled with fluid. A valve fluidly couples the second strain-sensing system to the lower enclosed section. The valve is operatively associated with the first strain-sensing system and is normally closed, preventing fluid in the lower section from communicating with the second strain-sensing system. The valve is constructed and arranged to open in response to a signal sent from the first strain-sensing system when the first strain-sensing system reaches an operating limit of strain measurement, thereby protecting the first strain-sensing system from being damaged from strains exceeding the operating limit thereof. The second strain-sensing system is constructed and arranged to measure the excessive strains.

    Abstract: A novel force measuring device of simple design is provided with complementary stop surfaces protecting the device against over-loading. Alternatively, overloading is prevented by duplicating the force measuring device with two portions operating in opposite directions of force application. Such force measuring devices are advantageously incorporated in couplings between a motor driven vehicle and a further vehicle to be coupled thereto. Signals derived from these force measuring devices are used in a board computer for controlling the operation of the motor driven vehicle and the further vehicle coupled thereto.
