Abstract: A process variable transmitter includes a process variable sensor, and an electromagnetic interference (EMI) protection circuit coupled to the process variable sensor. The process variable transmitter also includes a hermetic module enclosing the EMI protection circuit, and electrical connectors coupled to the EMI protection circuit within the hermetic module. The electrical connectors are configurable from outside the hermetic module to connect electronic components of the EMI protection circuit in a configuration that provides transient protection.

Abstract: A field device for an industrial process includes device circuitry, a shunt circuit, a bulk supply a charging power regulator and a supplemental circuit. The device circuitry is configured to receive power and communicate data over a two-wire process control loop. The shunt circuit is configured to shunt an unused portion of the power to an electrical ground. 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 wireless process variable transmitter for use in an industrial process includes a process variable sensor configured to sense a process variable of the industrial process. Measurement circuitry connected to the process variable sensor provides an output related to the sensed process variable. Wireless communication circuitry connected to the measurement circuitry wirelessly transmits information related to the sensed process variable to a remote location. A removable industrial power module is configured to hold a replaceable battery and provide power to the process variable sensor, the measurement circuitry and the wireless communication circuitry. Battery test circuitry in the removable industrial power module connects to the replaceable battery and provides a visual output related to a condition of the replaceable battery.

Abstract: An industrial process field device includes an active component, a switch, a switch monitor, and a controller. The active component may be a sensor configured to sense a process parameter, or a control device configured to control a process of the industrial process. The switch is electrically coupled to first and second terminals and is configured to electrically connect the first and second terminals when in a closed state, and electrically disconnect the first and second terminals when in an open state. The switch monitor is configured to detect a current state of the switch corresponding to the closed or open state, and generate a state output indicating the current state. The controller is configured to set the switch in the open or closed state, and generate a notification based on the state output that indicates at least one of the current state of the switch and a condition of the switch.

Abstract: A field device for an industrial process includes a current detector for detecting the amount of current consumed by the field device and an interface allowing the field device to communicate with at least one other device. The interface communicates a first alert when the amount of current consumed by the field device exceeds a first threshold and a second alert when the amount of current consumed by the field device is below a second threshold.

Abstract: A process transmitter includes a process variable sensor, a test circuit, a switch and a controller. The process variable sensor includes a sensor output that is indicative of a sensed process variable. The test circuit is configured to detect a condition of the process variable sensor. The switch is configured to selectively connect the test circuit to the process variable sensor and disconnect the test circuit from the process variable sensor. The controller is configured to obtain a measurement of the process variable, control the switch, detect a condition of the process variable sensor by comparing the sensor output when the test circuit is connected to the process variable sensor to the sensor output when the test circuit is disconnected from the process variable sensor, and communicate the condition in the measurement to an external control unit.
