<p>An inductance coil sensor in which a rotating spoiler (46) alters the inductance of a stationary coil (1230/1432) having two parts (12a, 12b; 30a, 30b/14a, 14b; 32a, 32b) disposed on opposite sides of the spoiler. Changes in inductance of the stationary coil are sensed to develop an indication of the rotary movement of the spoiler which, in turn, represents changes in the parameter being monitored. By locating one part of the stationary coil above the spoiler and one part below the spoiler, compensation is provided for undesired movements of the spoiler along its rotation axis.</p> |
