Abstract: The present invention is related to a connection system for connecting weighing cells to a connection cable, wherein the connection system has a housing with at least one plug-in connector for connecting a connection cable and at least one further plug-in connector for connecting at least one weighing cell. A method for operational monitoring of weighing cells is also provided. Using the connection system according to the present invention significantly simplifies the installation of one or more weighing cells and simultaneously minimizes the susceptibility to error. The object of monitoring the operation and the installation of weighing cells is achieved in that at least the states voltage supply, loop current, polarity reversal, and cable break are indicated.

Abstract: A force transducer for sensing the weight introduced into the mounting of a motor vehicle seat is disclosed. The force transducer includes a force introduction element that is connected to the motor vehicle seat, a force transfer element that is connected to the mounting, and an extension member that is arranged between the force introduction element and the force transfer element. The force transducer makes it possible to accurately determine the weight introduced into the mounting of the motor vehicle seat independently of other influencing forces by the fact that the force introduction element or the force transfer element surrounds the extension member in a plane that extends parallel to the effective direction of the weight, and that at least one wire strain gauge for sensing a shearing force parallel to the weight is arranged on the extension member.
