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 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 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 variable transmitter for use in an industrial process includes a housing having a cavity formed therein. The housing has a barrier which divides the cavity into first and second cavities. Measurement circuitry in the first cavity is configured to measure a process variable of the industrial process. A terminal block assembly is located in the second cavity. A moisture sensor has an electrical characteristic which changes based upon the presence of moisture in the second cavity.

Abstract: A two-wire process variable transmitter for use in an industrial process includes a process variable sensor configured to sense a process variable of a process fluid of the industrial process. Output circuitry provides an output on a two-wire process control loop which is related to the sensed process variable. Terminal voltage measurement circuitry measures a voltage at terminals of the process variable transmitter. The terminal voltage is a voltage measured across an electrical connection of the two-wire process variable transmitter to the two-wire process control loop. A microprocessor performs loop diagnostics on the two-wire process control loop based upon a loop current and the measured terminal voltage. The microprocessor determines coefficients of a polynomial equation which relates loop current and terminal voltage during normal operation of the two-wire process variable transmitter and performs subsequent diagnostics based upon the coefficients of the polynomial.
