General
Tolerance class	2
Diameter	4 mm

The extension cable for thermocouples from Chauvin Arnoux is a specific accessory for extending temperature sensor cables. It serves to extend the reach of thermocouples in measurement applications without impairing measurement accuracy. The cable is designed for use in laboratories, industrial environments, and other areas where a flexible and reliable connection of temperature sensors is required. It connects the temperature sensor to the measuring device or a control unit over a defined length, with the electrical properties of the cable meeting the requirements for thermocouple extensions.

Applications

The cable is intended for applications where the temperature sensor cannot be directly connected to the measuring device, for example, due to spatial distance or space requirements. It is particularly suitable for measurements in industrial process monitoring, research and development, and quality control. The temperature resistance from -40 °C to 100 °C makes it suitable for environments where ambient temperature fluctuates within this range. Tolerance class 2 ensures sufficient accuracy for many industrial and scientific applications.

Features and Equipment in Detail

The cable has a length of 1 meter and a diameter of 4 mm, enabling a compact and convenient design. One end is fitted with a male plug that fits directly into corresponding socket connectors. The other end consists of two stripped, bare wires, allowing direct connection to measuring devices, control panels, or other electrical systems. This construction allows flexible integration into existing installations without requiring additional adapters or conversion devices.

Technology Explained Simply

Thermocouples generate an electrical signal proportional to the measured temperature. To transmit this signal over longer distances without distortion caused by resistance or temperature gradients in the cable, the extension cable must be made of materials with the same thermoelectric properties as the thermocouple itself. The cable complies with tolerance class 2, meaning it exhibits a defined deviation from the ideal characteristic curve within the specified temperature limits, which is acceptable for the respective application. The temperature resistance from -40 °C to 100 °C ensures the cable remains mechanically undamaged and retains its electrical properties under these conditions.

Compatibility and Accessories

The extension cable is designed for use with thermocouples connected to the measuring device via a plug connector. It is not specifically intended for a particular thermocouple type (e.g., Type K, J, T) but serves as a general extension solution. Connection is made via the plug at one end and the bare wires at the other, making it compatible with various measuring systems that have corresponding connection options. No specific accessories are required to use the cable.

Installation and Mounting

Installation is carried out by simply plugging the plug into the corresponding socket on the measuring device or an intermediate amplifier. The bare wires at the other end are connected to the appropriate contacts according to the connection type, for example, by soldering, clamp connection, or crimping. The connection must be secure and correct to avoid measurement errors. The user instructions included in the delivery provide guidance on proper handling and installation.

Operational Advantages

The cable enables flexible placement of the temperature sensor independent of the measuring device's position. The compact design and clear connection configuration facilitate installation and maintenance. Tolerance class 2 and temperature resistance ensure reliable measurement under the specified conditions. The use of bare wires at one end provides flexibility when integrating into existing systems.

Scope of Delivery

The scope of delivery includes: 1 x extension cable for thermocouples (1 m) and 1 x user instructions. The user instructions contain information on the correct handling and installation of the cable.
