Abstract: A field device (100) for an industrial process includes device circuitry (106), a shunt circuit (126), a bulk supply (122), a charging power regulator (120), and a supplemental circuit (124). The device circuitry is configured to receive power and communicate data over a two-wire process control loop (104). The shunt circuit is configured to shunt an unused portion of the power to an electrical ground (128). The charging power regulator is configured to regulate an excess portion of the power to charge the bulk supply based on the unused portion. The supplemental circuit is powered by the bulk supply.

Abstract: A multiplexed input/output (I/O) system detects leakage currents on a selected input channel. The system includes a leakage detection multiplexer connected to provide an output selected from one of a plurality of input channels. In addition, the leakage detection multiplexer provides as part of the output measured leakage currents associated with the selected input channel. Based on the detected leakage currents, a determination can made regarding whether the detected leakage currents have compromised the integrity of the multiplexer output. In addition, the detected leakage current can be used to compensate the output provided by the multiplexer to account for the presence of leakage currents on the selected channel.

Abstract: A process sensor assembly comprises a hollow protective housing, a temperature sensor, a process transmitter, and a transient protector. The temperature sensor includes a probe extending out of the hollow protective housing to a sensing location, and a top plate movably secured to the hollow protective housing so as to allow travel within the hollow protective housing with vibrations of the probe. The process transmitter is configured to process and transmit sensor signals from the temperature sensor, and is retained on the top plate to move with the temperature sensor within the hollow protective housing. The transient protector is configured to condition power for to the process transmitter, and is anchored to the process transmitter so as to move with the process transmitter within the hollow protective housing.
