General
Tolerance class	2 -
Diameter	4 mm

The extension cable for thermocouples from Chauvin Arnoux is designed to extend the application range of temperature sensors. It enables bridging longer distances between the sensor and the measuring device, making installation more flexible and measurement points more accessible. The cable is specifically designed for use with thermometers of models C.A 1821, C.A 1822, TK 2000, TK 2002, as well as the data logger L642. Connection is made via a plug and socket at both ends, providing a secure and easy connection option.

Extension cable for thermocouples

The cable has a length of 1 metre and a diameter of 4 mm. These dimensions ensure sufficient mechanical stability and a stable electrical contact without impairing handling. The extension is designed for use in environments where the temperature ranges between -40 °C and 100 °C. This temperature resistance makes the cable suitable for many industrial and technical applications where the measurement point cannot be placed directly at the measuring device.

Tolerance class 2 and precise measurement

The extension cable meets the requirements of tolerance class 2, ensuring high accuracy in signal transmission. This is essential to avoid impairing the measurement accuracy of the connected thermocouples. Tolerance class 2 is widely used in industrial measurement technology and represents a standard for precise temperature measurements. The extension transmits the measurement signal without significant distortion, so that the values displayed on the device correspond to the actual temperatures.

At both ends of the cable, a plug and a socket are fitted. This design enables a quick and secure connection between the thermocouple and the measuring device. The plug connection is designed to compensate for mechanical stress and vibrations without affecting electrical conductivity. The connection is suitable for use in industrial environments where reliable signal transmission under real conditions is required.

The extension cable is specifically developed for the mentioned measuring devices from Chauvin Arnoux. It is not intended for other devices or thermocouple types, unless compatibility is explicitly confirmed in the device documentation. As an accessory, a self-supporting temperature sensor SK8 is offered, which also meets tolerance class 2 and is suitable for pipe installations. This sensor has a measurement range of -50 °C to 140 °C and a response time of 10 seconds at 63 % on stainless steel pipes with a diameter of 12 mm.

The delivery includes the extension cable (1 m) and user instructions. These instructions contain important information on the correct handling and installation of the cable to ensure optimal function and longevity.

The extension enables flexible placement of temperature sensors without impairing measurement accuracy. The plug-and-socket connection reduces installation time and facilitates maintenance. The cable is designed for use in environments with temperatures from -40 °C to 100 °C, making it suitable for many industrial applications. Tolerance class 2 ensures reliable signal transmission, so that the measurement results correspond to actual temperatures. The combination of length, diameter, and connection type provides a robust and practical solution for industrial use.
