Seamless Tube Armored Temperature Sensing Cable

Seamless Tube Armored Temperature Sensing Cable

Cable applications

Used for temperature and pressure sensing. The structure consists of bare fiber + gel + stainless steel seamless tube + sheath. This structured sensing cable features high tensile strength, crush resistance, good compactness, and excellent sealing and waterproof performance.
Used in oil tanks, mines, chemical and other industries for temperature or pressure sensing, to avoid disasters and accidents.

Cable features

Good mechanical performance, transmission performance and environmental performance.
Protected by a stainless steel seamless tube, with small outer diameter and high strength.
Sealed design, resistant to electrochemical corrosion, with water blocking and oil resistance.
