    Abstract: A pressure transmitter includes a process connector configured to mount to a process vessel that carries a process fluid, a process pressure sensor and an isolator plug coupled to the process connector and configured to house the process pressure sensor. The isolator plug includes at least one internal fluid filled cavity that is in fluidic contact with the process pressure sensor. At least one transfer mount made of a metallic material is coupled to the isolator plug. The transfer mount includes an internal fluid filled cavity that is in fluid communication with the internal fluid filled cavity of the isolator plug. At least one isolation diaphragm exposed to the process fluid in the process connector is coupled to the transfer mount and configured to transfer process pressure to the internal fluid filled cavities of the transfer mount and the isolator plug and to the process pressure sensor.

    CPC classification number: G06F1/3206

    Abstract: A field device for use in an industrial process includes a transducer configured to couple to the industrial process and control or monitor a process variable of the industrial process. Primary communication circuitry communicates information with a remote location related to the process variable. A wireless communication module includes an energy storage device and power monitoring electronics coupled to the energy storage device having a power output and a power status output. Wireless communication circuitry of the wireless communication module is configured to communicate wirelessly and perform a plurality of high priority tasks and a plurality of low priority tasks. The high priority tasks are performed asynchronously and the plurality of low priority tasks are only performed if the power status output indicates that there is sufficient power.

    CPC classification number: H02H9/02

    Abstract: A current limiting circuit for limiting a current through a pair of terminals powered from a 2-wire Advanced Physical Layer (APL) spur includes a current source, a first current limiter and a second current limiter. The current source is connected to one of the terminals and is configured to source a current that is conducted through the terminals and has an amplitude that is at a current source threshold. The first current limiter is connected to the current source and is configured to limit the amplitude below a first threshold. The second current limiter is connected to the first current limiter and is configured to limit the amplitude below a second threshold.

    CPC classification number: F16B2/08

    Abstract: A field device mount includes a union configured to couple to a field device. A clamp foot is coupled to the union and is configured to engage fluid handling equipment. A tensioner assembly is coupled to the clamp foot and includes a tensioner bracket. A biasing member is disposed to urge the tensioner bracket away from the clamp foot. A band is configured to pass around the fluid handling equipment and to couple to opposite sides of the tensioner bracket. A buckle is configured to provide clamping force to maintain tension in the band. A field device mount using inline tensioners or a v-bolt as well as a method of coupling a field device mount to fluid handling equipment are also provided.

    Abstract: A process oxygen analyzer includes a process probe extendible into a flow of process combustion exhaust, the process probe having an oxygen sensor measurement cell. Measurement circuitry is coupled to the oxygen sensor measurement cell and configured to obtain a non-corrected indication of oxygen concentration relative to a combustion process based on an electrical characteristic of the oxygen sensor measurement cell. A controller is operably coupled to the measurement circuitry and is configured to obtain an indication of process pressure and selectively provide a corrected oxygen concentration output based on non-corrected indication of oxygen concentration and the indication of process pressure. A method of providing a process oxygen concentration using a process oxygen analyzer coupled to an industrial combustion process is also disclosed.

    Abstract: A process temperature estimation system includes a mounting assembly configured to mount the process fluid temperature estimation system to an external surface of a process fluid conduit. A hot end thermocouple is thermally coupled to the external surface of the process fluid conduit. A resistance temperature device (RTD) is spaced from the hot end thermocouple. Measurement circuitry is coupled to the hot end thermocouple and is configured to detect an emf of the hot end thermocouple and a resistance of the RTD that varies with temperature and provide sensor temperature information. A controller is coupled to the measurement circuitry and is configured to measure a reference temperature based on the resistance of the RTD and employ a heat transfer calculation with the reference temperature, the emf of the hot end thermocouple, and known thermal conductivity of the process fluid conduit to generate an estimated process temperature output.
