FORCE-MEASURING MODULE FOR A FORCE-MEASURING DEVICE USING A PLURALITY OF SUCH MODULES

摘要

A multiple force-measuring device, especially a multiple weighing device has at least two force-measuring modules. Each force-measuring module includes a force-measuring cell and a power delivery means. The power delivery means of at least one of the force-measuring modules in this arrangement is connected, directly or through a junction element, to a control cable that is connected to a power supply unit. The force-measuring modules are connected directly to each other through a module-connection cable that transfers electrical power therebetween.

主权项

1. A force-measuring module for use in a force-measuring device having a plurality of the force-measuring modules, the force measuring device also having a terminal, a power supply and a plurality of connection cables, arranged to form a chain that transmits communication signals bi-directionally between the terminal and the force-measuring modules and that transmits power uni-directionally from the power supply to the force-measuring modules, each force-measuring module comprising:
a housing; a force-measuring cell, arranged in the housing to receive a force imposed thereupon and generate a measurement signal proportional to the imposed force; a communication means, arranged in the housing to receive a measurement signal from the force-measuring cell and to communicate bi-directionally with the terminal; a power delivery means, arranged in the housing to receive power from the power supply and to distribute the power within the housing; and a link of the chain, comprising:
a first plug connector, arranged on the housing and configured on the exterior thereof for connection to a first of the plurality of connection cables; anda second plug connector, arranged on the housing and configured on the exterior thereof for connection to a second of the plurality of connection cables;wherein, on the interior of the housing, the bi-directional communication signals and the uni-directional power transmitted by the chain through the respective connection cables are linked through at least the first and second plug connectors, the communication means and the power delivery means.
