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 and provide a process variable sensor output. A battery power source includes a plurality of battery power banks each having a primary cell battery, a low voltage cut-off circuit electrically connected to the primary cell battery which provides an electrical connection to the primary cell battery while a voltage of the primary cell battery is above a threshold, and an ideal diode having an input electrically connected to the primary cell battery through the low voltage cut-off and providing a power bank output. A power sharing node has an input connected to the battery power bank output of each of the plurality of battery power banks and having a shared power output which provides power to circuitry of the wireless process variable transmitter.

Abstract: A wireless field device for use in monitoring acoustic noise includes an acoustic sensor configured to sense acoustic noise. Processing circuitry coupled to the acoustic sensor is configured to identify a hazardous noise condition based upon the sensed acoustic noise and a personnel noise exposure standard. Output circuitry provides a warning output in response to an identified noise condition. A system is also provided which uses one or more acoustic sensors implemented in wireless field mounted monitors.

Abstract: An acoustic measurement system for an industrial process asset includes a process measurement device providing a value representative of an acoustic signal near the industrial process asset based in part on a signal from an acoustic sensor positioned near the industrial process asset. A second acoustic sensor provides an acoustic value and a noise reduction component uses the acoustic value from the second acoustic sensor to affect the value provided by the process measurement device so that the value provided by the process measurement device is more representative of an acoustic signal generated by the industrial process asset.

Abstract: A gauge system comprises a sensor that produces a sensor signal as a function of a sensed parameter. The gauge system also comprises a motor and a gauge having a scale and a movable indication needle that is driven by the motor and displays a measurement value of the sensed parameter based upon position of the needle relative to the scale. The gauge system further includes a position sensor that produces a position feedback signal representative of a sensed position of the needle and a controller that provides drive commands to the motor based on the sensor signal and the position feedback signal.
