Summary:A pressure transmitter for use in measuring a pressure of a process fluid in an industrial process. The pressure transmitter includes a pressure sensor having a pressure output related to the pressure of the process fluid. Measurement circuitry is configured to calculate a process variable of the process fluid based upon the pressure output. Diagnostic circuitry diagnoses operation of the industrial process based upon a process parameter of the pressure output. Process parameter calculation circuitry calculates the process parameter based upon pressure output and reduces the effect of an abrupt change in the pressure output on the calculated process parameter.
