ABSTRACT:
In a down hole gauge signals from a plurality of parametric sensors are processed through a multiplexer and analog to digital converter and stored alternately in digitized binary format in a solid state memory for subsequent readout above the well surface. A preprogrammed solid state clock initiates measurement sequences and deactivates all circuits between sequences.
