摘要： A measuring device for measuring a physical quantity includes a sensor arrangement connected by a signal conductor to an amplifier arrangement. The sensor arrangement generates a measurement signal and includes an RFID transponder. The amplifier arrangement includes an RFID write and read device that is capacitively coupled to the RFID transponder. Data for transmission via the signal conductor are modulated onto high-frequency electrical signals.

摘要： A method is provided for controlling an injection molding system, which includes a mold having an inner surface defining at least two groups of cavities, each group of cavities defining precisely one cavity with one pressure sensor at the inner surface. Each group of cavities is at least partially surrounded by a tempering unit that provides an energy flow to the surrounded cavities. According to the method, a pressure is determined in each group of cavities of the at least two groups of cavities. A reference pressure is determined for each group of cavities. A difference between the reference pressure and the pressure in at least one group of cavities is determined and controlled to become minimum by manipulating the energy flow of the tempering unit.

摘要： An acceleration transducer defines a rectangular coordinate system with two orthogonal horizontal axes that are both normal to a vertical axis and includes a main body defining tangential side faces arranged tangentially to the vertical axis, and normal side faces arranged normally to the vertical axis. The transducer includes at least a first piezoelectric element secured to one the three tangential side faces, and exactly one seismic mass is secured to the at least one piezoelectric element, which has a high sensitivity for a shear force exerted by the attached seismic mass along a principal tangential axis and a low sensitivity for a shear force exerted by the attached seismic mass along another one of the three axes.

摘要： An acceleration transducer defines a rectangular coordinate system with two orthogonal horizontal axes that are both normal to a vertical axis and includes a main body disposed within a housing and defining tangential side faces arranged tangentially to the vertical axis, and a normal side face arranged normally to the vertical axis. A piezoelectric element is secured to one of the tangential side faces, and a seismic mass secured to the piezoelectric element. A signal output is attached to the housing and includes a signal conductor spaced apart by an assembly gap from a tangential side face that is not attached to the piezoelectric element. The assembly gap extends perpendicularly to the vertical axis. The normal side face includes main body output conductors spanning the assembly gap in a direction perpendicular to the vertical axis and directly contacting the signal conductor.

摘要： A transducer for determining a pressure of a hydrogen-containing fluid medium confined in a first space includes a pressure side end configured to be disposed facing the fluid medium. The transducer includes a housing, which defines a second space, and a measuring arrangement disposed in the second space. The pressure side end includes a diaphragm configured and disposed for hermetically separating the first space from the second space. The diaphragm includes a metallic material that is made of a high-alloy martensite.

摘要： A system for chip-removing machining of a workpiece and for measuring and evaluating force and torque during the chip-removing machining of the workpiece includes a machine tool with a tool for chip-removing machining of the workpiece; a device for measuring force and torque during chip-removing machining of the workpiece; and an evaluation unit for evaluating measured value data of the device. The measuring device includes a measuring unit installed in the machine tool and rotates with the tool about an axis of rotation during chip-removing machining. The evaluation unit is stationary. The measuring unit generates measured values of force and torque. The measuring device includes a control unit that transmits measured values as measured value data in a wireless manner directly to the evaluation unit with a transmission power in the range of 0.1 mW to 10 mW.

摘要： A device for detecting a rail load fits into a bore of a rail and includes a sensor that generates a load signal under an action of the rail load caused when rail vehicles with wheels travel on the rail and the wheels exert a load onto the rail. The load signal is a measure for the rail load. The sensor includes at least one piezoelectric sensor element that generates electric polarization charges as the load signal.

摘要： Tool holder comprising a tool receptacle, a machine interface, and a sensor receptacle. The tool receptacle is configured to releasably receive a tool having at least one cutting edge for machining a workpiece. The machine interface is configured to enable the tool holder to be fastened to a machine tool. In the sensor receptacle, a sensor is arranged that is configured to generate a measurement signal that is dependent on a force acting on the tool holder The sensor receptacle is spaced apart from both the tool receptacle and the machine interface, so that the sensor is neither in direct contact with the tool nor in direct contact with the machine tool when the tool is accommodated in the tool receptacle and the tool holder is fastened to the machine tool.

摘要： A method for determining the measurement uncertainty of a measuring system that detects a physical measurement variable includes a plurality of transmission links forming a measuring chain for detecting a physical measurement quantity. Directly adjacent transmission links are in a cause-and-effect relationship in the measuring chain. The method includes using a computer program to read in information for identifying the transmission links; reading in legible labels of influencing variables of the transmission links identified by the computer program product; determining a relevance of the influencing variables of the identified transmission links for the computer program's measurement uncertainty; and using influencing variables determined as being relevant for calculating the computer program's measurement uncertainty.
