ABSTRACT:
A logging sonde includes a tube defining a sealed chamber inside. An isolation layer is disposed on an exterior of the tube. At least one sensor is disposed on an exterior of the isolation layer. The sensor includes a lead in passing through a wall of the tube. An elastomer jacket is disposed on an exterior of the sensor and the isolation layer. A method for making a sonde includes affixing an electrically insulating isolator to an exterior of a tube. An hydraulic seal layer is affixed over an exterior of the isolator. A sensor is affixed over the exterior of the seal layer. An electrical connection is made from the sensor to an interior of the tube through the hydraulic seal layer and through the isolator. An elastomer jacket is applied over the exterior of at least part of the sensor and the exterior of the seal layer.
