What is an Instrumentation Cable?

Instrumentation cables are designed to carry low-power, low-current signals between field instruments and control systems. They are specially constructed to minimize electrical noise and ensure accurate signal transmission even in harsh industrial environments.

Key Features

• Shielding: Reduces EMI and RFI interference.
• Twisted pairs: Minimize crosstalk between adjacent signals.
• Durability: Resistant to temperature, chemicals, and mechanical stress.
• Flame retardant options: Improve safety and compliance with standards.

Typical Applications

• Process automation and control systems
• Transmitter (4–20 mA) and sensor connections
• Monitoring and data acquisition systems

Types of Instrumentation Cables

• Unarmoured Cable: For indoor or protected installation.
• Armoured Cable: For mechanical protection in outdoor or hazardous areas.
• Shielded Cable: With individual and overall shields to reduce noise.

💡 Tip: Always terminate the shield at one end only to prevent ground loops and interference.
