ABSTRACT:
A temperature-compensated measuring system employs an internal signal-processor to provide high accuracy measurements, correct over a wide range of temperatures. In a calibration mode, the system employs the signal-processor to provide mathematical constants used to generate a temperature-compensation function. In a measurement mode, signals representing the uncompensated quantity and the system temperature are supplied to the signal-processor, which uses them to generate a temperature-compensation function from which it produces a high-accuracy temperature-corrected value of the measured quantity. In various forms, the invention can be used to measure temperature-compensated force, pressure or acceleration.
