Abstract: A device for transmitting an electrical current through a bulkhead, with the bulk-head having an opening therein. The bulkhead has a first side that is under a pressure. The device includes a housing, fitted within the opening, a pin contact operatively positioned within the housing, and a solder cup operatively associated with the pin contact. A generating member, operatively adapted to the solder cup, for generating an electrical current representing a measured physical parameter within the bulk head is included. The device further comprises a sleeve member adapted for coupling the generating member, the pin contact and the solder cup so that the electrical current is transmitted from the generating member to the pin contact. A sealing mechanism is included so that the pressures within the bulkhead are prevented from migrating through the device.

Abstract: Apparatus for detecting corrosive conditions in pipelines comprises a wire having an electric potential different from the electric potential of the pipeline. The wire is disposed in the pipeline in a housing which prevents it from coming into contact with a pig used to clean the interior of the pipeline. The wire is spaced from the interior of the pipeline so that it normally is not in direct electrical contact with the pipeline. The wire extends out of the pipeline and is electrically connected to an indicator. The indicator is also electrically connected to the pipeline. When corrosive fluid, such as briny water, is present in the pipeline and comes into contact with the wire and the interior of the pipeline, an electric current is electrochemically produced due to the difference in electric potential between the pipeline and the wire. The indicator detects this current and indicates that corrosive conditions are present in the pipeline.
