Abstract: A diagnostic device (100) for use in a industrial process includes monitoring electronics or diagnostic circuitry configured to diagnose or identify a condition or other occurrence in the industrial process. The system can be implemented in a process device such as a flowmeter, and in one example an acoustic flowmeter. A transducer can also be used and a frequency response, such as resonant frequency, can be observed.

Abstract: A two-wire field-mounted process device (16) with multiple isolated channels includes a channel that can be an input channel or an output channel. The given input or output channel can be coupled to multiple sensors or actuators (32, 34), respectively. The process device (16) is wholly powered by the two-wire process control loop (14). The process device (16) includes a controller (40) adapted to measure one or more characteristics of sensors (20, 22, 24, 26, 28, 30) coupled to an input channel (42, 44, 46) and to control actuators coupled to an output channel (48). The controller can be further adapted to execute a user generated control algorithm relating process input information with process output commands. The process device also includes a loop communicator (36) that is adapted to communicate over the two-wire loop.
