In 2019, Duchin Instrument accepted the commission from COMAC (Commercial Aircraft Corporation of China, Ltd.) Shanghai and participated in the MIIT's (Ministry of Industry and Information Technology) 'Special Scientific Research on Civil Aircraft - Research on On-site Calibration Technology and Measurement Guarantee Digital Demonstration Platform for Key Performance Parameters of Thermal Processing Equipment' on the 'Development of Consumable Thermocouples' sub-project. The flexible thermocouple developed by us is insulated with high silica fiber and shielded by heat-resistant steel wire. It complies with AMS2750 and ASTM/E574 standards. It has a max temperature measurement of 1000℃, 1st class accuracy, and a head-to-tail deviation of no more than 0.6℃. There is no odor when first used, can be used multiple times at the max temperature.

Derived from the technology of flexiable thermocouples,Duchin develop Multi-Circuit Thermocouple Extension Cable Harness Improves Cable Connections and Reduces Setup Time for High-Pressure Sterilizers.

The Multi-point Thermocouple Extension Cable Harness offers an improved cable connection solution and reduces setup time for high-pressure sterilization applications. Available in 6, 12, or 24 cable configurations, this extension cable harness features multi-pin connectors on one end and free-floating independent male or female connectors on the other end. The design ensures both accuracy and long-term reliability.

The thermocouple cable connection can be performed on composite components using hot tool thermocouples or lead/lag thermocouples in preparation for high-pressure sterilization. Once the component is placed in the autoclave, the corresponding cable harness can be quickly connected to its component thermocouple, dramatically reducing setup time.

VI. Frequently Asked Questions

1. How to choose between Type J and Type K thermocouple cables?

Answer: It should be determined according to the supporting thermocouple type and temperature measurement scenario: Type J thermocouple cables are suitable for temperature measurement range of -40~750℃ and resistant to reducing atmospheres; Type K is suitable for -200~1300℃ and resistant to oxidizing atmospheres, with a wider applicable temperature range, making it the mainstream choice in industry. When selecting, ensure that the cable type is consistent with the thermocouple type to avoid thermoelectric potential deviation.

2. Can the product be used in non-high-pressure sterilization scenarios?

Answer: Yes. The core advantages of this product are efficient connection and standard compliance. In addition to high-pressure sterilization equipment, it can also be widely used in industrial high-temperature temperature measurement systems, scientific research experimental equipment and other scenarios requiring multi-point temperature measurement and quick docking, as long as the temperature measurement temperature matches the cable tolerance range.

3. Is there any limit to customized cable length?

Answer: The cable length can be customized according to customer needs, with no strict length limit. However, it is recommended to choose reasonably according to the actual installation spacing. Excessively long cables may cause signal attenuation, which can be optimized by adding shielding layers or consulting the manufacturer for the best length recommendation; specific installation scenarios and spacing data should be provided during customization to ensure adaptability.

4. Is special treatment required before initial use?

Answer: No special treatment is needed. The product uses high-quality insulation materials such as high silica fiber, with no initial odor. It can be directly wired and used according to the identification after unpacking; before use, check whether the connector pins are intact and the cable is damaged to ensure a firm connection.

5. How to ensure the service life of the cable in high-temperature environments?

Answer: ① Ensure that the operating temperature does not exceed the rated tolerance range of the product (insulation and connector ≤200℃, supporting flexible thermocouple ≤1000℃); ② Avoid excessive bending, pulling of the cable or friction with sharp objects to prevent damage to the sheath and shielding layer; ③ Regularly check the sealing performance of the connector and the appearance of the cable, and replace it in time if damage is found to avoid affecting insulation and signal transmission.

6. Does the product support docking with thermocouples of other brands?

Answer: Yes. The connector pins of the product are designed according to general standards. As long as the type (Type J/K) and interface specifications of the docked thermocouple match the cable, compatible docking can be achieved; it is recommended to confirm that the accuracy class of the thermocouple is consistent with the cable before docking to ensure the overall temperature measurement accuracy.
