Methods and apparatus to define an interconnect node for a submersible sensing cable

A submersible sensing cable comprising:

• a jacket;
• a node defined by the jacket, the node separating first and second wire portions of the sensing cable;
• a first mechanical support to define a first end of the node;
• a second mechanical support to define a second end of the node opposite the first end;
• a circuit board extending between the first and second mechanical supports;
• a sensor electrically coupled to the circuit board;
• and
• a potting material filler at least partially surrounding the circuit board.

A method for producing a submersible sensing cable, the method comprising:

• coupling a circuit board to a first support at a first end of the circuit board;
• coupling the circuit board to a second support at a second end of the circuit board opposite of the first end of the circuit board;
• terminating a first wire portion to the first support;
• terminating a second wire portion to the second support;
• and
• providing a potting material to at least partially surround the circuit board.
