Abstract
A single sensing unit having two electrodes with a common thermal reference is positioned near the centroid of the inertial mass of a differential inductive accelerometer. As the mass is displaced a first sensor detects an increase in inductance while a second sensor detects a decrease in inductance. Significantly, the first and second sensors share a common thermal reference eliminating any thermal differential. As the sensor system is closely aligned with the centroid of the inertial mass the sensor system of the present invention reduces or eliminates any systemic error.
