    Abstract: An improved oxygen analyzer includes a controller configured to receive an oxygen sensor signal and provide an oxygen concentration output. A probe is configured to extend into a source of combustion process gas. An oxygen sensor is disposed within the probe and has a sensing electrode mounted to one side of a solid electrolyte and a reference electrode mounted to an opposite side of the solid electrolyte. The oxygen sensor has catalytic beads that are configured to be disposed between the process gas and the sensing electrode. Measurement circuitry is operably coupled to the oxygen sensor and the controller and is configured to provide the controller with the oxygen sensor signal based on an electrical response of the oxygen sensor. The controller is configured to detect a behavior of the oxygen sensor concentration output over time to provide at least one ancillary output.

    Abstract: A field device for an industrial process includes a digital isolator which electrically divides the field device into a primary side for low voltage electronics from a secondary side. A device power supply located in the secondary side is configured to provide power to a process control device which monitors or controls a process variable of the industrial process. A latching relay located in the secondary side couples to the process control device and the device power supply and has a set input to responsively couple the device power supply to the process control device and a reset input which causes the latching relay to enter an electrically open state to thereby disconnect the device power supply from the process control device. A controller located in the primary side is configured to generate a switch signal. The digital isolator extends between the primary side and the secondary side and couples to the switch signal from the controller and provides a digital output on the secondary side in response to the switch signal. Edge triggered circuitry couples to the digital output of the digital isolator and provides a pulse output to the reset input of the latching relay in response the digital output of the digital isolator.

    Abstract: A process fluid pressure transmitter includes a pressure sensor body containing a pressure sensor that has an electrical characteristic that changes in response to applied pressure. An isolation diaphragm is configured to be exposed to process fluid. A fill fluid fluidically couples the isolation diaphragm to the pressure sensor. A weld ring is welded to the isolation diaphragm at a first weld. A barrier metal is disposed on at least one surface of the isolation diaphragm such that the barrier metal extends over the first weld. The weld ring is welded to the pressure sensor body at a second weld that is spaced from the barrier metal.

    Abstract: A temperature sensor assembly includes a temperature sensor body having a bore defined therein. The bore has a first internal surface feature and a second internal surface feature. A cap is disposed within the bore of the temperature sensor body proximate an end of the temperature sensor body. A temperature sensitive element is disposed within the cap. A first elastomeric ring is disposed about the cap and configured to interact with the first internal surface feature of the temperature sensor body. A second elastomeric ring is disposed about the cap and spaced from the first elastomeric ring. The second elastomeric ring is configured to interact with the second internal surface feature of the temperature sensor body. A wireless field device including the temperature sensor assembly is also provided.

    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.
