System and process for providing a display arrangement on a device that may be limited by an intrinsic safety barrier
First Claim
1. A display arrangement for providing information visible at an observation location, comprising:
- a light producing device operable to generate light, and electrically limited by an intrinsically safe barrier; and
an intermediary layer provided at a position between the observation location and the light producing device, the intermediary layer being electrically limited by the intrinsically safe barrier, and capable of one of blocking and reducing intensity of at least a portion of the light generated by the light producing device.

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.
