Abstract: An electromechanical joining module for applying a linear force to a joining element, includes a stator, which represents the stationary part of the joining module, a tappet, which can be linearly extended out of the stator and which has an outer tappet end, and a force transducer for detecting forces that are applied to the joining element during the operation of the tappet end. The force transducer is attached in the area of the tappet end and has sensor electronics for wirelessly transmitting measurement data by means of near-field and far-field telemetry.

Abstract: The invention relates to a tool having a tool element which rotates in operation with at least one geometrically defined blade, in particular a material cutting tool element. The tool element is subject to an operating parameter in the operating condition. A measuring device is provided for determination and conversion of the operation parameter into a measured signal. A first measuring device cooperates with a first tool element in the operating condition such that essentially only a first operating parameter for the first tool element may be recorded by the first measuring device.

Abstract: A piezoelectric sensor for bending moment measurements has measuring elements separating at their axes and electrically connecting both halves with their opposing directions of polarization. Such a sensor, mounted with its axis on the neutral bending axis of a machine structure, thus measures concurrently both tension and compression of the machine on both sides of the axis thereof.

Abstract: A strain gauge measures elongation and compression at a surface of a component. The strain gauge comprise a housing having a fixation configured to attach the strain gauge to the surface to be measured, a connector for contacting a measuring cable, at least two support surfaces at the housing for securely bearing on the surface to be measured. At least one of the support surfaces is provided with a transduction element and with a measuring element for measuring shearing forces. The measuring element is connected by an internally disposed cable to the connector and to a module that comprises that at least one support surface provided with the measuring element pre-assembled together with the transduction element.

Abstract: For a comparative material testing of similar formed parts based on their dynamic behaviour under acoustic excitation vibrations, in order to obtain clear-cut information about the material properties it is necessary to assure constant excitations of the vibration generator and a constant pressing force when coupling this to the object being tested. This is accomplished by using a piezoelectric actuator in an assembly unit with an electromechanical sensor and a coupling element, whereby the excitation voltages of the actuator are monitored and its vibrations passing into the formed part are registered by the sensor.
