Abstract: A barrier device (2) threadably mounts to a cabling aperture (24) on a field mounted transmitter (6). The field mounted transmitter (6) receives and transmits signals, and is wholly powered by a current loop circuit (14). The barrier device (2) has a conductive housing with at least a first (72) and a second (74) aperture and a pair of conductors (14) passing through the first aperture (72) of the barrier device (2), for connecting to a terminal block (4) in the transmitter (6). A pair of signal terminals (16, 18) are mounted in the second aperture (74) of the barrier device (6). The signal terminals (16, 18) are connectable to a handheld communicator, which is used to calibrate, monitor and test the transmitter (6). A barrier circuit (22) is mounted in the housing and is electrically connected between the signal terminals (16, 18) and the conductors (14).

Abstract: A two-wire process variable transmitter (12) for use in an industrial process, including a process variable sensor (14) configured to sense a process variable of a fluid of the industrial process. Output circuitry (36) is configured to provide an output on a two-wire process control loop (18) which is related to the sensed process variable. Loop current measurement circuitry (36) measures a loop current flowing through the two-wire process control loop (18) and terminal voltage measurement circuitry (36) measures a voltage related to a terminal voltage of the process variable transmitter (12). The terminal voltage can be a voltage measured across an electrical connection of the two-wire process variable transmitter (12) to the two-wire process control loop (18). Input circuitry (36) is configured to receive a diagnostic command from the two-wire process control loop (18). A microprocessor (30) configured to perform loop diagnostics on the two-wire process control loop (18) based upon the measured loop current and terminal voltage in response to receipt of a diagnostic command from the two-wire process control loop (18).
