Abstract

A process and a device for the remote interrogation of measuring points is offered that form at least one group belonging together spatially and that supply electric measuring signals that are supplied separately to a central evaluation station. The distinction of this process and this device according to the invention is that the measuring signals from each of the measuring points forming one group are supplied in each case via an associated signal transmission device, preferably one (if necessary two-wire) line first to a network device assigned to the respective group, which holds the measuring signals receive from its measuring points for successive switching to its input and that for each network device the measuring signals are switched through control signals led via its input in a predetermined sequence to its input which is connected directly or indirectly with an input of the central evaluation station.
