MANOMETER WITH LIGHT GUIDE, MONITORING DEVICE AND GAS DISTRIBUTION DEVICE EQUIPPED WITH THE MANOMETER

摘要

The invention deals with a display comprising a manometer 4 of the common type and a light guide 6 of annular cross section disposed around the housing of the manometer in such a way as to emit a luminous signalling radiation around the manometer and essentially directed towards an observer of said manometer. The display is intended to be integrated into a display surface 18 in such a way as to allow optimal visualization of the information. The activation of the light guide is dependent on electrical signals reflecting a binary state such as in particular the exceeding of a pressure threshold or the detecting of a valve or any control member in a given position. The light guide can comprise one or more luminous sources of different colours. The invention also deals with a device for distributing gas and a monitoring device for such a distributing device, equipped with one or more displays according to the invention.
