Abstract
A new class of accelerometer uses a differential Eddy current sensor to sense the displacement of the proof mass. This accelerometer can provide improved performance in an open-loop configuration based on the thermal stability and improved linearity of the differential Eddy current sensor. The accelerometer may provide lower cost alternatives to commercial grade accelerometers and lower cost and higher reliability alternatives to strategic grade accelerometers.
