3 Core Teflon RTD Cable for Temperature Sensors

A. Product Overview

Teflon/Teflon 3 Core RTD Cable is designed for connecting RTD temperature sensors to controllers, indicators, transmitters and monitoring instruments. The cable has three internal conductors covered with Teflon, also known as PTFE insulation.

PTFE insulation is known for its high temperature resistance, chemical resistance and excellent electrical insulation properties. Because of this, the cable is suitable for industrial environments where normal PVC or rubber insulated wires may fail due to heat, oil, chemicals or harsh working conditions.

This cable is commonly used with RTD sensors in motors, control panels, heaters, industrial machinery, process equipment and temperature measurement systems.

B. Working Principle

An RTD sensor works by changing its resistance according to temperature. When the temperature increases or decreases, the resistance value of the RTD element also changes. This signal is then sent to a temperature controller, indicator or transmitter.

The 3 core RTD cable carries this resistance signal from the RTD sensor to the measuring instrument. In a 3-wire RTD connection, the extra wire helps reduce the effect of lead wire resistance, which improves temperature measurement accuracy compared to a simple 2-wire connection.

The Teflon insulation protects the conductors from heat, chemicals and electrical leakage, helping the RTD signal remain stable and reliable in industrial applications.

C. Why It Is Used

Teflon/Teflon 3 Core RTD Cable is used because temperature sensor wiring often passes through hot, oily, chemical or electrically sensitive environments. A normal wire may become hard, damaged or unreliable in such conditions.

This cable is used for:

Reliable RTD temperature sensor wiring
High temperature industrial applications
Better electrical insulation
Chemical resistant wiring
Motor temperature monitoring
Control panel wiring
Heater and furnace temperature sensing
Industrial process temperature measurement
Reducing signal error in 3-wire RTD connections
Longer cable life in harsh environments

The main benefit of this cable is that it helps maintain accurate and stable temperature signal transmission between the RTD sensor and the measuring instrument.
