Temperature-humidity surveillance equipment

A measurement cable surveillance provision for pipe-like containers of fluids for continuous temperature and humidity sensing comprising

• a first electrical conductor wire;
• a second electrical condutor wire running substantially parallel to the first electrical conductor wire and where the first and the second conductor wire are substantially similar;
• a hygroscopic insulator means disposed between the first and the second electrical conductor wires for providing humidity control and for spacing said conductor wires at a predetermined distance relative to each other;
• a humidity permeable insulator surrounding the hygroscopic insulating means and the first and second electrical conductor wires;
• a helically disposed resistance wire for temperature sensing purposes running on the outside of the humidity permeable insulator and about along the electrical conductor wires and disposed at a spaced distance from the first and the second electrical conductor wires.
