摘要： An intrinsically safe redundant regulator circuit includes a plurality of voltage limiting regulators between a regulated rail and a ground rail. Each of the plurality of voltage limiting regulators includes: (i) a shunt regulator component configured to clamp a voltage across the regulated rail and the ground rail to a safety clamp voltage value; and (ii) one or more components, where a property of each of the one or more components is selected to configure the safety clamp voltage value.

摘要： An apparatus includes a housing, a touch sensor, a display, and a control module. The housing has a body defining a volume to accommodate a process control device and is adapted to withstand a threshold internal pressure greater than an external pressure. The housing further has a transparent portion having first and second surfaces. The touch sensor is disposed adjacent to the second surface of the transparent portion and senses an input received within a minimum distance from the first surface of the transparent portion. The display is disposed adjacent to the touch sensor and displays at least one adjustable variable corresponding to the process control device.

摘要： A diagnostic device is physically coupled to a control device in a process control system, and includes an accelerometer that determines when a motion or vibration of the control device is greater than a predetermined threshold. When this condition is detected, one or more other components of the diagnostic device (e.g., processor, communication module, etc.) are activated, and a distress signal is transmitted from the diagnostic device using the activated components. Consequently, the duty cycles of components of the diagnostic device are decreased and optimized, leading to significant power savings. Indeed, in some embodiments, energy harvesting may be sufficient to power the diagnostic device. Further, in some embodiments, the diagnostic device may not require a component processor.

摘要： An accelerometer wireless position transducer or sensor is physically coupled to a control device in a process control system and includes an accelerometer that generates a signal based on a position of the control device or its actuator. The transducer converts the accelerometer signal into a wireless signal that includes a value indicative of the actuator position, and causes the wireless position feedback signal to be transmitted over a wireless channel to a valve controller, e.g., by using a short-range wireless protocol. The controller controls the valve based on the value included in the wireless signal. In some configurations, the feedback signal is received at a device paired with the transducer, and the paired device transmits the feedback signal to the controller. The paired device may be paired with multiple transducers and/or sensors, and may transmit various feedback signals to multiple recipient controllers and other devices.
