Weighing apparatus with alignment of accelerometer coordinate system and load cell coordinate system and related method

A weighing apparatus, comprising:

• a load cell assembly comprising:
• an elongated load cell body including a first three-dimensional coordinate orientation defined by a first X-axis, a first Y-axis and a first Z-axis, the elongated load cell body including a mount end for supporting the elongated load cell body and a load end for applying a load to the elongated load cell body, the elongated load cell body carrying a set of strain gauges for providing electrical outputs corresponding to load applied to the load end of the elongated load cell body;
• an accelerometer unit operatively connected to the elongated load cell body in a fixed position relative to the elongated load cell body, the accelerometer unit having a second three-dimensional coordinate orientation that is not aligned with the first three-dimensional coordinate orientation and that is defined by a second X-axis, a second Y-axis and a second Z-axis, wherein the second X-axis is offset from the first X-axis, the second Y-axis is offset from the first Y-axis and the second Z-axis is offset from the first Z-axis;
• a memory unit operatively connected to the elongated load cell body, the memory unit storing a rotation matrix M that defines data for aligning the second three-dimensional coordinate orientation of the accelerometer unit with the first three-dimensional coordinate orientation of the elongated load cell body.
