Electro-pneumatic converter calibration. |
摘要 |
<p>A temperature compensation method for a microprocessor based electro-pneumatic converter device (10) including an initial calibration sequence, a compensation sequence, and an operation sequence. Linearization of an electro-pneumatic positioner including the steps of adjusting the positioner feedback linkage (30) until a predetermined reference position is attained, reading a position feedback value and determining the required feedback linearization value to achieve a linear relationship between the output/input. A calibration method and a configuration method independent of calibration for a microprocessor based electro-pneumatic converter device (10) including an initial calibration sequence, a configuration sequence, and an operation sequence. <IMAGE></p> |
