Variable condition responsive sense system and method

摘要

Signal conditioning of multiple sense elements is shown for providing information to a system requiring high accuracy and robust fault coverage. A first signal conditioning ASIC ( 10 ) pre-conditions the sense element data and a second system control ASIC ( 14 ) mathematically solves predetermined compensation relations based on the output of ASIC ( 10 ) and stored compensation data to fully condition the sensor output signal(s). The sense elements ( 1 - 6 ) are each formed by two half bridges whose inputs are pre-conditioned by separate, identical signal conditioning paths to provide highly accurate sense and diagnostic information.
