Kapton Insulated Thermocouple Wire

A. Product Overview

Kapton and Kapton thermocouple wire is a special type of thermocouple cable insulated with Kapton, a high-performance polyimide film known for its excellent temperature resistance, chemical resistance, and electrical insulation properties.

This wire is used to connect thermocouple sensors with temperature indicators, controllers, transmitters, data loggers, and monitoring systems. The Kapton insulation helps protect the thermocouple conductors from heat, chemicals, abrasion, moisture, and electrical interference.

Kapton insulated thermocouple wire is preferred in demanding applications where normal insulation materials such as PVC or rubber may fail due to high temperature or harsh working conditions.

B. Working Principle

A thermocouple wire works on the principle of temperature difference between two dissimilar metals. When the thermocouple junction is exposed to temperature, it generates a small voltage signal. This signal is then carried through the thermocouple wire to a temperature measuring instrument.

In Kapton and Kapton thermocouple wire, the Kapton insulation protects the conductors while allowing the temperature signal to travel accurately from the sensor point to the measuring device. The insulation does not measure temperature directly, but it helps maintain signal reliability by protecting the wire from external damage, heat, chemicals, and electrical leakage.

C. Why It Is Used

Kapton and Kapton thermocouple wire is used because it provides reliable performance in high-temperature and harsh industrial environments.

It is mainly used for:

• High-temperature temperature measurement
• Thermocouple sensor wiring
