Downhole gauge assembly

A downhole gauge assembly comprising:

• a gauge housing including a receiving aperture defined by an inner sealing surface of the gauge housing,
• a gauge arranged in or in association to the gauge housing,
• a metal cable with an inner bore in communication with and extend into an interior of the gauge housing, wherein the metal cable extends from a downhole location of a subsurface well up to a top of the subsurface well,
• an electrical or optical conductor extending through the inner bore of the metal cable, wherein the electrical or optical conductor is connected to the gauge through an electrical or optical connector,
• wherein the electrical or optical connector is arranged within the gauge housing and is configured to, at least, extend to said receiving aperture of the gauge housing;
• wherein the inner sealing surface of the gauge housing abuts and seals against an outer surface of the metal cable;
• wherein the electrical or optical connector has an elongated cylindrical shape with a diameter in a range between an outer diameter of the metal cable and a diameter of the inner bore of the metal cable.
