Abstract

The present invention includes an as a gas and/or liquid sensor (2') serving light-waveguide, into which is fed, from a light transmitter, an incoming light, and from which is transmitted, to a light detector, an outgoing light, whose spectral range is evaluable in a spectral analysis device. Said light-waveguide (2') is applied to, or is formed as, a part of a carrier (15), in the form of a stable substratum, as a loop. The outer surface of the waveguide is completely or partly exposed and adjacent waveguide sub-sections (22, 23) are closely packed. The invention likewise includes an arrangement to, from a central unit, supervise and/or affect one, out of several, selectable peripheral units, suitably using a light-waveguide, by through a light-conductive waveguide (71) transmitting and receiving information in the form of coded light bundles or light-pulses.
