The SK20 Flexible Sensor from Chauvin Arnoux is a K-type thermocouple sensor designed for general temperature measurements. It features a flexible sensor made of Inconel 600, a high-quality nickel-chromium metal known for its heat resistance and corrosion resistance. The sensor is 1 m long and has a diameter of 1.5 mm, ensuring good flexibility and sufficient mechanical stability. It is designed for measurements in the range of -40 °C to +450 °C and complies with Tolerance Class 1, ensuring high accuracy in temperature measurement. The response time is 1 second at 63 % of the final value, enabling rapid response to temperature changes.

Applications

The SK20 is suitable for a wide range of applications in industrial measurement technology, particularly in areas requiring flexible and robust temperature measurement. It can be used, for example, in process monitoring, maintenance and servicing, as well as in quality control. The use of Inconel 600 makes it especially suitable for environments with high thermal stress or aggressive chemicals.

Features and Equipment in Detail

The sensor is equipped with compensated miniature connectors, ensuring a secure and reliable electrical connection. These connectors allow for easy installation and interchangeability. The probe is designed for use with various devices from Chauvin Arnoux, including the thermometers C.A 1821, C.A 1822, TK 2000 and TK 2002, as well as the data logger L642. Additionally, it can be used with an adapter as an accessory for multimeters, increasing its flexibility in use.

Technology Explained Simply

A K-type thermocouple sensor operates based on the Seebeck effect, where a temperature difference between two different metals generates an electrical voltage. This voltage is measured and converted into a temperature value. Tolerance Class 1 means that the deviation of the measured temperature from the actual value lies within a defined tolerance range specified for this class. The response time of 1 second at 63 % of the final value describes how quickly the sensor reacts to a temperature change – a value important for precise and timely measurements.

Compatibility and Accessories

The SK20 is compatible with thermometers C.A 1821, C.A 1822, TK 2000 and TK 2002, as well as the data logger L642. It can also be used with an adapter as a multimeter accessory. Using it with these devices enables precise and reliable temperature measurement in various application scenarios. The compensated miniature connectors ensure a secure connection and facilitate easy replacement of the sensor.

Installation and Mounting

The SK20 is mounted using the integrated miniature connectors, which are plugged into the corresponding connections on the measuring devices. The flexible design of the sensor allows for easy placement at various measurement points. No additional fastening is required, as the sensor can be adapted to the respective measurement point by its flexibility and length.

Operational Advantages

The SK20 offers high measurement accuracy due to Tolerance Class 1 and a fast response time of 1 second. The use of Inconel 600 ensures high mechanical and thermal load capacity, extending the sensor’s service life. Interchangeability and compatibility with various devices increase the product’s flexibility and reusability. The compensated miniature connectors ensure a reliable electrical connection, stabilizing the measurement results.
