ABSTRACT:
A load cell assembly includes a load cell body having a pair of sensors mounted therein which provide complementary output signals in response to a force applied to the load cell body. A linearization and common mode discrimination routine analyzes changes in the sensor outputs and characterizes the changes as being either primarily due to applied force or primarily due to common mode effects. A force value, indicative of the applied force on the load cell body, is updated only for changes in the sensor outputs which are primarily due to applied force. However, changes which are primarily due to common mode effects are not incorporated into force value calculations, whereby common mode effects are rejected.
