摘要： A process variable transmitter system for sensing a first pressure at a first location and second pressure at a second location, includes a first transmitter (110) having a first pressure sensor (202) configured to sense the first pressure and first analog output stage (204) coupled to the first sensor (202) configured to provide an analog output signal related to the first pressure. A second pressure transmitter (112) includes a second pressure sensor (202) configured to sense the second pressure and spaced apart from the first pressure sensor (202). A second analog output stage provides an analog output related to the second pressure. An analog processing stage provides a processed output related to the first and second pressures. A two-wire output (140) is configured to provide an analog current output on a two-wire process control loop based upon the processed output.

摘要： A field mountable dedicated process diagnostic device is used for diagnosing operation of an industrial control or monitoring system. An input is configured to receive at least one process signal related to operation of the industrial process. A memory contains diagnostic program instructions configured to implement a diagnostic algorithm using the process signal. The diagnostic algorithm is specific to the industrial process. A microprocessor performs the diagnostic program instructions and responsively diagnoses operation of the process based upon the process signal.
