1. A system for use in monitoring conditions within a borehole, comprising:

  • a length of conduit extending from the surface through the borehole down to the zone where the monitoring is to occur;

    a telemetry link module mounted on the lower end of the conduit for transmitting information to the surface, said telemetry link module having means positioned at its lower end for receiving a sensor module and coupling information produced by said sensor module into said telemetry link;

    a communication cable connected between the telemetry link and the surface extending through the length of conduit;

    means for pumping from the surface down the conduit into the monitoring region adjacent the telemetry link a fluid which provides a medium conducive to accurate inspection of the conditions within the borehole by the sensor module;

    a sensor module couple to the receiving means of said telemetry link module, said sensor module including an outer housing, an inner equipment chamber and a passageway therebetween coupled for fluid communication with a passageway within said telemetry link module and receiving the flow of fluid pumped from the surface to cool said sensor module; and

    of tubular struts attached to the end of said outer housing of said sensor module opposite said telemetry link module, each of said struts having one end in fluid communication with the passageway within said sensor module housing and the other end open to discharge fluid flowing therethrough into the borehole being inspected.
