Abstract: A rotatable assembly and a method to use the same are provided. In particular, the assembly includes a first field device housing arrangement associated with a first electrical system, and a second field device housing arrangement associated with a second electrical system are connected by a connector arrangement. The connector arrangement may include probes (e.g., spring probes) that are adapted to engage with contacts (e.g., electrical contacts), and is configured to allow an unrestricted rotation of the first field device housing arrangement relative to the second field device housing arrangement while maintaining a continuous electrical coupling between the first electrical system and the second electrical system. For example, the assembly can be a field device, such as a smart field device. Two devices may be secured to one another by use of a captive locking screw which can be used to secure the first device in desired positions.

Abstract: A system for measuring at least one parameter is provided. The system includes a control logic arrangement powered by a power source, and an intrinsically safe barrier operatively connected to the control logic arrangement, and also powered by the same power source. The intrinsically safe barrier is adapted to be operatively connected to at least one sensor which is also powered by the same power source. The sensor is configured to communicate data representing a parameter to the control logic arrangement via the intrinsically safe barrier. In one embodiment, the control logic arrangement, the intrinsically safe barrier and the sensor are galvonically isolated from external components and/or provided in one enclosure.

Abstract: An arrangement and method for determining one or more characteristics of a sample fluid, and a method to determine the one or more characteristic of the sample fluid, are provided. In particular, a first assembly is contained within a particular housing, and a second assembly is positioned externally from the particular housing. The first assembly includes a first sensor which may be adapted to obtain first data associated with a first characteristic of the sample fluid, and a particular electrical assembly which is electrically coupled to the first sensor, and may be adapted to determine the first characteristic of the sample fluid as a function of the first data. The second assembly includes a second sensor which may be adapted to obtain second data associated with a second characteristic of the sample fluid.

Abstract: A data acquisition method and system for obtaining digital samples are provided. A first digital sample related to an analog signal is obtained after a first time period. A second digital sample related to the analog signal is obtained after a second time period. The second digital sample is provided on at least one output if magnitudes of the first digital sample and the second digital sample differ from one another by a predetermined threshold.

Abstract: A displaceable display and a method for controlling an output of a display unit are disclosed. The display arrangement includes a circuit board, a display unit, a detector and a controller. The display unit communicates with the circuit board. The display unit is capable of rotating with respect to the circuit board and being placed in at least one particular orientation with respect to the circuit board. The detector automatically detects the particular orientation of the display unit with respect to the circuit board. The circuit board transmits signals to the controller and the controller routes the signals to output of the display unit as a function of the particular orientation.
