About this product

Globally Trusted Thermocouple Compensating Cables

At Elegar Kerpen, one of the most trusted wires and cables manufacturers in India, our thermocouple and compensating cables are manufactured to IS:8784, IEC 60584, ASTM E230, BS, ANSI-MC 96.1, and DIN standards. Produced at our ISO-certified facility with exact emf characteristics for every thermocouple type, they deliver cost-effective, dependable temperature measurement for power plants, chemical facilities, furnaces, and process industries across 40+ countries.

What a thermocouple compensating cable does
Thermocouple and compensating cables extend the millivolt signal from the sensing junction to control instrumentation without distorting the reading. Their conductors use alloys with matched thermo-electric properties, so the connection to pyrometers, controllers, recorders, and data acquisition systems introduces no measurable error across the rated ambient range.

Support FAQ

Frequently Asked Questions

Common technical and commercial questions about Elegar Kerpen thermocouple and compensating cables.

What is a thermocouple compensating cable?
A thermocouple compensating cable extends a thermocouple signal from the sensing point to instrumentation. It uses similar — not identical — alloys and maintains accurate temperature measurement within the ambient range at a lower cost than extension-grade thermocouple cable.
How many types of cable are there in thermocouple cables?
Thermocouple cables include extension grades (JX, KX, TX, EX, NX) and compensating types (KCB/KCA, RCB/SCB, NC, BC). They are classified by thermocouple type and temperature range, ensuring compatibility, signal accuracy, and reliable measurement in industrial applications.
What is thermocouple cable used for?
Thermocouple cable transmits millivolt signals from thermocouple sensors to controllers or recorders. It is widely used in furnaces, power plants, chemical processing, HVAC systems, plastic moulding, and food processing for accurate temperature monitoring and process control.
Is there a need for customised joints or terminations?
Yes. Proper thermocouple connectors, matching polarity, and compatible extension or compensating cable types are essential. Incorrect joints introduce measurement errors. For critical temperature monitoring systems, use thermocouple-grade terminals and follow ANSI or IEC colour coding standards.
Can I use compensating cable to make a thermocouple?
No. Compensating cable does not use the exact thermocouple alloy pair required for the Seebeck effect. It is designed only for signal transmission, not for forming a thermocouple sensing junction.
Will using compensating cable affect my temperature readings?
Slightly, if used beyond its rated ambient temperature range. Within specified conditions, compensating cable maintains acceptable accuracy for most industrial temperature measurement and process control applications.
Why not always use extension cable?
Extension cable provides better accuracy because it uses matching thermocouple alloys. However, it is more expensive. Compensating cable offers a cost-effective solution for signal transmission in moderate ambient environments.
What temperatures can PVC-insulated compensating cable handle?
PVC-insulated compensating cable typically handles ambient temperatures between 70°C and 105°C, depending on insulation grade. For higher temperatures, consider PFA, fibreglass, or silicone-insulated thermocouple cables.
How do I know which compensating cable type to buy?
Match the compensating cable to your thermocouple type. For example, a Type K thermocouple requires KCB compensating cable. Correct pairing ensures signal integrity, measurement accuracy, and reliable industrial temperature monitoring.
Do thermocouple cables need screening or shielding?
In most industrial installations, yes. Millivolt-level signals are easily corrupted by electromagnetic interference from motors, drives, and adjacent power cabling. Aluminium foil or braided screening, earthed at one end only, preserves signal integrity over long cable routes.
