Process variable compensation in a process transmitter
Abstract:
A process variable transmitter includes a process variable sensor having a process variable sensor output related to a sensed process variable. Analog compensation circuitry is configured to receive the process variable sensor output and responsively provide a compensated process variable sensor output based upon a compensation function which is responsive to a control input. Output circuitry provides an output based upon the compensated process variable. Digital control circuitry is coupled to the analog compensation circuitry providing a control output which is applied to the control input of the analog compensation circuitry to thereby control the compensation function.
