HYSTERETIC PROCESS VARIABLE SENSOR COMPENSATION

摘要

A process variable transmitter (36) for sensing a process variable of an industrial process includes a process variable sensor (56) configured to sense a current process variable of the industrial process. Measurement circuitry (74) is configured to compensate the sensed process variable as a function of at least one previously sensed process variable characterized by a Hysteron basis function model. Output circuitry (78 80) provides a transmitter output related to the compensated sensed process variable.
