General
Tolerance class	2
Diameter	4 mm

The extension cable for thermocouples from Chauvin Arnoux is a specialised component for extending the reach of temperature sensors. It enables a secure and precise connection between thermocouples and measuring instruments, transmitting electrical signals over a length of 1 metre. The cable is designed for use in laboratories, industrial plants, and other environments where flexible and reliable temperature measurement is required. It features tolerance class 2, ensuring high accuracy in temperature measurement, and is designed for temperature resistance from -40 °C to 100 °C, making it suitable for a wide range of applications.

Applications

The cable is primarily intended for extending thermocouples to spatially separate the measurement point from the measuring instrument. This is particularly necessary when the measurement point is located in hard-to-reach or space-limited areas, such as machine chambers, pipelines, or mobile measurement setups. The operating temperature range of -40 °C to 100 °C covers both cool and moderately warm environments, making it suitable for many industrial and scientific applications. Its robust construction allows for safe use in environments with mechanical stress or low contamination risk.

Functions and Equipment in Detail

The cable has a length of 1 metre and a diameter of 4 mm, resulting in a compact and easy-to-handle design. At both ends, it features two banana plugs and a socket, enabling a secure mechanical and electrical connection to measuring instruments or other thermocouple extension cables. The use of banana plugs ensures simple and quick installation, as well as stable contact, which is essential for precise measurement results. Tolerance class 2 corresponds to a high accuracy standard for thermocouple extensions, ensuring that measurement deviations remain within specified limits.

Technology Explained Simply

Thermocouples generate an electrical voltage signal proportional to the temperature difference between the measurement point and the reference point. When extending the cable, it is essential that the extension cable matches the thermocouple type to avoid additional voltage drops or measurement errors. This extension cable is specifically designed for this purpose and complies with tolerance class 2, meaning it operates within the specified tolerances and thus does not compromise measurement accuracy. The temperature resistance from -40 °C to 100 °C ensures the cable remains stable even under extreme environmental conditions, without mechanical or electrical defects.

Compatibility and Accessories

The cable is designed for extending thermocouples and can be connected to other extension cables or measuring instruments equipped with banana plug connectors. It is not specifically designed for a particular thermocouple type (e.g. Type K, J, T), but serves as a general extension solution. Connection is made via banana plugs and sockets, which are widely used in measurement technology. It does not include special accessories such as protective tubes, insulating materials, or additional connectors.

Installation and Mounting

Installation is performed by simply plugging the banana plugs into the corresponding sockets of the measuring instruments or other extension cables. No special tools or additional mounting aids are required. The connection is mechanically stable and allows for quick installation. The 1-metre length provides sufficient flexibility to separate the measurement point from the device without making cable routing overly complex. Handling is easy due to the cable’s compact and lightweight design.

Operational Advantages

The extension cable enables flexible and precise temperature measurement without compromising measurement accuracy. Tolerance class 2 ensures high reliability of measurement values. The use of banana plugs ensures a quick and secure connection that remains stable even with frequent plugging and unplugging. The temperature resistance from -40 °C to 100 °C makes the cable suitable for a wide range of applications without requiring additional protective measures. The compact design facilitates storage and transportation.

Scope of Delivery

The product is delivered with one thermocouple extension cable (1 m) and user instructions.
