ABSTRACT:
A sensor assembly is coupled with a control linkage and detects displacement of the control linkage and produces an output signal indicative of that displacement. The zero-point of the sensor assembly is not necessarily aligned with the zero-point of the control linkage when the two systems are coupled together. Instead, the control linkage is placed in its zero position and the sensor assembly determines its current positional reading at that time. This reading is stored as a zero-offset value which is then used, during normal operation of the sensor, to adjust the output signal of the sensor assembly when subsequent control linkage displacements are sensed.
