FIELD: electricity.
SUBSTANCE: voltage is changed at least at one of the electrodes. Movable mass (MM) shifts determined by these voltage variations are measured by means of measuring the change of capacity between one of the electrodes and MM. Clearance is determined using shift-voltage dependence, got by calculation from following expression: M(α, d, u)+cα = 0, where: M - moment, created by electric field when voltage is supplied to one of the electrodes; α, d - tilt angle and clearance between MM and electrodes; c - resilient suspension stiffness of MM. Device for clearance measurement contains computing device which inputs are connected with voltage source and capacity-voltage converter outputs.
EFFECT: increase of clearance accuracy measurement.
