1. Apparatus for detecting unlevelness in a pendulously supported flux valve comprising a source of alternating current signals, means to apply a vertically oriented alternating magnetic field across said flux valve in response to said alternating current signals, means to receive voltages induced in each leg of the flux valve by said alternating magnetic field, means to resolve said induced voltages into quadrature components having a predetermined orientation with respect to said flux valve, means to provide output signals indicative of the magnitude and phase of each quadrature component with respect to said alternating current signals, and means for graphically displaying said output signals.
