Abstract
A modular force-measuring cell is disclosed which includes a force transducer equipped with sensors that measure changes occurring in the state of the force transducer as a result of a force or temperature. The force-measuring cell also includes a memory module for storing compensation data associated with the modular force-measuring cell. The memory module and at least one converter circuit for the conversion of the signals delivered by the sensors are arranged in a circuit module that is mechanically and thermally coupled to the force transducer.
Claims22
A modular force-measuring cell comprising:
- a force transducer equipped with sensors that measure changes of the force transducer as a result of a force or temperature;
- a memory module for storing compensation data associated with the modular force-measuring cell;
- and
- a circuit module mechanically and thermally coupled to the force transducer, wherein said circuit module comprises the memory module, at least one converter circuit for converting analog signals delivered by the sensors, and a connector terminal arrangement through which the memory module and the converter circuit each are connectable separately to a processor module, wherein the processor module is spatially set apart from the force-measuring cell to provide a thermal uncoupling between the processor module and the force measuring cell.
