Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a tensile-resistant and breakage-resistant sensor cable. Background Technology

[0002] Sensor cables are specialized cables used to connect sensors to measurement, control, or signal processing equipment. They are responsible for converting physical quantities detected by sensors (such as temperature, pressure, flow rate, displacement, etc.) into electrical signals and transmitting them accurately and stably to the measurement, control, or signal processing equipment. However, the tensile strength and breakage resistance of existing sensor cables often fail to meet actual requirements. During installation, laying, and long-term use, they are easily subjected to external forces such as stretching, bending, and torsion. When their mechanical strength is insufficient, they are prone to breakage, leading to signal interruption and affecting equipment operation. This problem is more pronounced in environments with frequent movement or vibration, increasing maintenance costs and downtime. Utility Model Content
