  • Patent number: 10416185
    Abstract: Systems and methods are disclosed for generating temperature compensated acceleration data in both analog and digital format from a torque balance accelerometer (TBA). During manufacture of the TBA, a calibration process is used consisting of cooling and heating the TBA to discrete temperatures within a range and at each discrete temperature measuring the TBA scale factor and offset. After collecting scale and offset data, said data is loaded into the memory of the TBA. During field operation, sensing a current temperature, retrieving the closest scale and offset correction factors from memory of the TBA, and performing linear interpolation to generate a temperature-compensated output for the TBA.
