About this product

Global Instrumentation Cables

Modern industrial operations depend on precision monitoring and control, where even minor signal disruptions can compromise process efficiency and safety. At Elegar Kerpen, one of the most trusted wires and cables manufacturers in India, instrumentation cables are engineered to the exacting requirements of power plants, chemical processing facilities, oil and gas installations, and advanced manufacturing units. ISO-certified manufacturing and our E-beam technology with hybrid crossfire capability deliver cables that hold signal integrity and operational reliability across the most demanding projects.

What an instrumentation cable does
Instrumentation cables form the communication backbone between field sensors and control rooms, carrying low-level analogue and digital signals over considerable distances while protecting them from electromagnetic interference, moisture, and the harsh conditions typical of industrial sites. Twisted pairs and screening keep signals intact between sensors, transmitters, PLCs, and DCS systems.

Support FAQ

Frequently Asked Questions

Common technical and commercial questions about Elegar Kerpen instrumentation cables.

What is an instrumentation cable?
An instrumentation cable is a low-voltage signal cable designed for accurate data transmission in industrial process control systems. Twisted pairs and screening protect against EMI and hold signal integrity between sensors, transmitters, PLCs, and DCS systems.
How many types of cable are used in instrumentation?
The range covers individually shielded, collectively shielded, and individually plus collectively shielded types, along with armoured instrumentation cables, thermocouple extension cables, and multipair cables. Each type suits specific applications based on EMI protection, mechanical strength, and signal transmission requirements.
What is instrumentation cable used for?
They are used in process control systems, industrial automation, oil and gas plants, power generation, and water treatment facilities, carrying low-voltage analogue and digital signals from sensors to PLCs and DCS for accurate monitoring and control.
Is there a need for customised joints or terminations?
Yes. Proper termination is essential for maintaining signal integrity and shielding continuity. Specialised terminal blocks, connectors, and grounding methods are recommended, particularly in high-EMI or hazardous industrial environments.
