Abstract: A sensor apparatus for wellbore applications includes an electrical conductor extending within an armored tubular jacket to protect the electrical conductor. The electrical conductor is isolated from wellbore fluids when the sensor is placed in a wellhead flange by redundant seals such that the tubular jacket around the conductor does not provide a leak path to the surrounding subsea or surface environment. To isolate the electrical conductor, a connector housing may be provided that establishes a seal with the electrical conductor. For example, a glass-metal seal or a PEEK-metal seal may be established between the electrical conductor and the connector housing. The connector housing may be welded or otherwise sealed to a Christmas tree flange that connects to the wellhead flange. The welds and seals of the sensor apparatus may be proof tested to ensure their effectiveness before the Christmas tree flange is installed in the subsea or surface environment.
