Abstract: An arrangement and method are provided to avail information visible at an observation location is provided. The arrangement includes a sensor adapted to sense at least one process parameter and a display for providing a visual representation of the at least one process parameter received from the sensor. The sensor can be electrically limited by an intrinsically safe barrier, and is capable of being powered in accordance with a fieldbus protocol. The display is electrically limited by an intrinsically safe barrier, and is capable of being powered in accordance with the fieldbus protocol. The display may include a light producing device for generating light and an intermediary (or light blocking) layer. The intermediary layer can be positioned closer to the observation location than the light producing device, and may be configured to selectively block or reduce the intensity of a portion of the light generated by the light producing device.
