Abstract:
Systems and methods are disclosed for generating temperature compensated acceleration data in analog and digital format from a torque balance accelerometer (TBA). During manufacture of the TBA, a calibration process is used for measuring a TBA scale factor and offset. After collecting scale and offset data, said data is loaded into the memory of the TBA. Field operation of the device includes: 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.
