Abstract: A thermowell assembly for use in measuring a temperature of a process fluid includes an elongate thermowell body configured to mount to a process vessel and extend into the process fluid. An elongate bore extends along a length of the thermowell body from a proximal end of the thermowell body proximate a wall of the process vessel to a sealed distal end of the thermowell body positioned in the process fluid. A side bore extends from an exterior of the thermowell assembly to the elongate bore. The side bore is positioned outside of the process vessel. A verification valve includes an inlet coupled to the side bore at the exterior of the thermowell assembly and further includes an outlet.

Abstract: An industrial process monitor for monitoring an industrial process includes a controller configured to control operation of the industrial process monitor. An ambient environment sensor is configured to sense an ambient environment of the industrial process proximate the device and responsively provide a sensor output signal. Output circuitry is configured to provide an output based upon the sensor output signal. The controller causes the ambient environment sensor to enter a high power mode upon detection of an anomaly and/or probable anomaly in the sensor output signal.

Abstract: A field device for monitoring a process variable of an industrial process includes an image capture device. A process component exhibits relative motion as a function of a process variable. The image captures device captures an image which changes due to the relative motion of the process component. An image processor coupled to the image capture device detects relative motion of the process component and measures the process variable based upon the detected relative motion. Output circuitry provides an output related to the measured process variable.

Abstract: A remote seal assembly for a process transmitter includes a seal body containing a cavity sealed by a diaphragm. The seal body configured to be mounted to a process element containing a process fluid such that a first side of the diaphragm is exposed to the process fluid. A capillary contains a fill fluid that is in fluid communication with the cavity and a second side of the diaphragm. A coupling has a capillary recess and two cavities separated by a second diaphragm. The capillary extends through the capillary recess and connects to the coupling such that the fill fluid in the capillary is in fluid communication with one of the two cavities and the second diaphragm. A thermally conductive element preferably extends continuously along the capillary from the seal body toward the coupling and into the capillary recess without contacting the coupling.

Abstract: A display assembly with a software rotatable content layout for a process control transmitter. The assembly has a display screen configured for displaying the rotatable content layout in a plurality of configurations and at least one physical button fixedly positioned proximate one side of the display screen. In one embodiment, the display layout comprises an upper perimeter band and a lower perimeter band reserved for displaying at least one label and a right side band and a left side band reserved for displaying an indicator attached to the at least one label and a third, interior region reserved for displaying additional text such that the at least one label is visually attached to the physical button proximate the one side of the display screen. The display is rotatable to maintain content in a viewer orientation such that at least one label is visually tied to at least one physical button in each of the plurality of configurations.

Abstract: A process fluid temperature estimation system includes a sensor capsule having a temperature sensitive element disposed therein configured to sense an external surface of a process pipe. The process fluid temperature estimation system includes measurement circuitry coupled to the sensor capsule and configured to detect a characteristic of the at least one temperature sensitive element that varies with temperature and provide sensor capsule temperature information and a controller coupled to the measurement circuitry, the controller being configured to obtain a reference temperature and employ a heat transfer calculation with the reference temperature and the sensor capsule temperature information to generate an estimated process temperature output. The process fluid temperature estimation system includes a mounting assembly configured to mount the process fluid temperature estimation system to the external surface of the process pipe, wherein a portion of the mounting assembly is offset from the external surface of the process pipe.

Abstract: A method of joining a brittle material to a component is provided. The method includes depositing a metallization layer on a surface of the brittle material. A layer of joining material is applied between the brittle material and the component, such that the component and the brittle material define an interface area. The metallization layer and the joining material layer extends beyond the interface area.

Abstract: A process transmitter includes a circuit producing a plurality of digital values representing magnitudes for an analog signal and a filter receiving the plurality of digital values and producing a plurality of filtered digital values. Output analog circuitry in the process transmitter is configured to receive the filtered digital values and output an analog signal on a communication channel of the process transmitter. The output analog circuitry has a transfer function and the filter has a transfer function. The transfer function of the filter at least partially offsets the transfer function of the output analog circuitry.
