System for acquiring and recording signals delivered by a set of sensors disposed in well probes

Image Number 3 for United States Patent #4901289.

A system is provided for acquiring and recording signals delivered by a set of sensors disposed in one or more probes lowered into a well at the end of a multi-function cable.The different signals to be transmitted are multiplexed before being applied to an acquisition chain adapted for amplifying them, digitizing them and coding them before applying them to a transmission channel in the form of blocks of digitized words. The multiplexing means may comprise several multiplexing units. The sampling frequency of each signal and the formation of the blocks of words are adapted to the number of units effectively used. In the surface installation, the blocks of words are dissociated and stored in a memory in a single mode suitable for all the blocks whatever their formation.
