Abstract
An improved rotor imbalance detector for a centrifuge comprising a rotatable electrically conducting ring; means to support and insulate the conducting ring from the centrifuge spindle shaft, and yet permit rotational movement of the conducting ring with respect to the support means, when the conducting ring is struck by the centrifuge drive spindle during an imbalance condition, means for de-energizing the power supplied to the centrifuge motor which rotates the drive spindle, and an electrically conducting lead in electrical contact with the conducting ring and the de-energizing means.
