Description
The K-Type PTFE Thermocouple Extension Cable is designed to accurately extend the low-voltage millivolt signal from a K-Type thermocouple to temperature controllers, PLCs, DCS systems, indicators, recorders, and data acquisition systems without compromising measurement performance. Unlike thermocouple-grade cable, which forms the sensing junction, an extension cable is specifically manufactured for reliable signal transmission over longer distances, helping maintain measurement accuracy while allowing instrumentation to be installed safely away from the sensing point. It is widely used in industrial temperature measurement, process control, and automation systems where dependable thermocouple signal transmission is essential.
Manufactured using high-quality K-Type extension-grade conductors with PTFE insulation, this cable offers excellent resistance to heat, chemicals, moisture, oils, solvents, and abrasion, making it suitable for demanding industrial environments. The durable construction provides stable electrical performance and helps minimize signal interference during transmission. An optional armoured (YOS) construction adds mechanical protection against impact, crushing, and physical damage, making it ideal for exposed cable runs in factories, refineries, power plants, and heavy industrial installations. The cable is supplied in a 100-meter spool with a 250V insulation rating, providing flexibility for new installations, plant expansions, and maintenance projects.

FAQs
1. What is a K-Type PTFE Thermocouple Extension Cable?
A K-Type PTFE Thermocouple Extension Cable is designed to extend the millivolt (mV) signal from a K-Type thermocouple sensor to a temperature controller, PLC, indicator, recorder, or data acquisition system without significantly affecting measurement accuracy. It is specifically manufactured for signal transmission rather than temperature sensing.
2. What is the difference between a Thermocouple Extension Cable and a Thermocouple Cable?
A Thermocouple Extension Cable carries the temperature signal from an existing thermocouple sensor to the measuring instrument, whereas a Thermocouple Cable (Thermocouple-Grade Wire) forms the actual sensing junction that measures temperature. Extension cables are intended solely for accurate thermocouple signal transmission.
3. Why is PTFE Insulation used in Thermocouple Extension Cables?
PTFE insulation provides excellent resistance to chemicals, moisture, abrasion, and elevated temperatures while offering superior electrical insulation. This makes PTFE thermocouple extension cables ideal for chemical plants, pharmaceutical facilities, oil & gas, power plants, and other demanding industrial environments.
