US 8,076,595 B2 · Method for transmitting measurement values in a multi-module force-measuring device, multi-module force-measuring device, and force measuring module

Abstract

A method and associated apparatus transmits measurement values in a multi-module force-measuring device, in particular a multi-module weighing device, with at least two force-measuring modules. Each of the force-measuring modules includes a force-measuring cell and a signal-processing unit. The signal-processing unit transmits the measurement values generated by the force-measuring cell by way of a signal line to a signal-evaluating unit. Under the method, each measurement value is converted into a bit sequence by the respective signal-processing unit. The first force-measuring module's bit sequence is transmitted to the signal-evaluating unit, and the bit sequences of the signal-processing unit of the further force-measuring modules are transmitted by way of the signal-processing unit of the first force-measuring module to the signal-evaluating unit.

A method for transmitting measurement values in a multi-module force-measuring device with at least two force-measuring modules, each of which comprises a force-measuring cell and a signal-processing unit which transmits the measurement values generated by the force-measuring cell by way of a signal line to a signal-evaluating unit, comprising the steps of:

converting the measurement values of each force-measuring module in the associated signal-processing unit into a bit sequence;
transmitting the bit sequence of the first force-measuring module to the signal-evaluating unit;
and
transmitting the bit sequence of each subsequent force-measuring module by an intermediate connector line to the signal-processing unit of the first force-measuring module, and, from there, to the signal-evaluating unit.
