1. A process device for diagnosing operation of an industrial process or process device, comprising:
- diagnostic circuitry configured to diagnose operation of the industrial process or process device based upon a process noise signal sensed by a sensor configured to sense the process noise signal;
a process coupling for coupling the process device to process fluid of an industrial process, comprising;
a process interface configured to physically couple to the process fluid and having an opening which opens to the process fluid;
a fluid pathway extending from the opening of the process interface to the sensor and which terminates at the sensor, the fluid pathway configured to couple the sensor of the process device to the process fluid; and
wherein the fluid pathway is configured to amplify at least a portion of the process noise signal from the process fluid to the sensor.

Abstract
A process coupling for coupling a diagnostic device to process fluid of an industrial process includes a process interface configured to physically couple to the process fluid. A fluid pathway extending from the process interface configured to couple a process interface element of the process device to the process fluid. The fluid pathway is configured to optimize transmission of process noise from the process fluid to the process device for use by the diagnostic device.

14. A method for diagnosing operation of an industrial process or process device, comprising:
-
coupling a field device to the industrial process with a process coupling having an opening which opens to a process fluid; receiving a process noise signal from the process fluid with the opening of the process coupling and coupling the process noise signal to a sensor of the field device, wherein the coupling includes a fluid pathway from the opening to the sensor which terminates at the sensor; altering the process noise signal by amplifying at least a portion of the process noise signal with a physical configuration of the process coupling; sensing the altered process noise signal with the sensor of the field device; and diagnosing operations of the process or process device based upon the sensed altered process noise signal. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
