Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...
Abstract: A novel fluxgate current sensor scheme based on a dual-core configuration is proposed in this study. By integrating a direct current (DC) zero-flux detector, an alternating current (AC) zero ...
Abstract: The displacement sensor is of vital importance for the levitation control of the active magnetic bearing (AMB). For the most widely used eddy current sensor (ECS), it is easy to be affected ...
