摘要:
A method for correcting offsets in sensors includes mounting, on a rotating machine, a first set of sensors in locations selected to measure vector loads in a first set of coordinates. The method further includes mounting, on the rotating machine, a second set of sensors in locations selected to measure vector loads in a second set of coordinates, wherein the first set of coordinates and the second set of coordinates rotate with respect to one another when the rotating machine is operating. The method also includes utilizing measurements from either or both of the two sets of sensors to correct offset errors in vector loads measured by the other set of sensors.
