en.Wedoany.com Reported - Yudian temperature control technology products have been selected for the petrochemical industry's "14th Five-Year Plan" textbook, "Principles and Applications of Industrial Control Equipment," with its AI-8 series digital controller fully included in the "Process Control Instruments" chapter. Yudian is the only digital controller brand featured in this textbook, with products suitable for measuring, displaying, and precisely controlling industrial process parameters such as temperature, pressure, liquid level, and flow.
"Principles and Applications of Industrial Control Equipment" is a series of textbooks for automation majors in higher education institutions, organized by the China Chemical Education Association and published by the Chemical Industry Press, holding authoritative status in China. In the "Process Control Instruments" chapter, the textbook uses the AI-8 series digital controller as a teaching example, systematically analyzing equipment selection, panel functions, wiring methods, and practical application scenarios.
The textbook explicitly states that Yudian has achieved a technological leapfrog over imported instruments, made breakthroughs in the domestic substitution of digital controllers, and its technical indicators comprehensively lead imported counterparts, "truly embodying the spirit of craftsmanship." This inclusion in the textbook helps students grasp the principles of high-precision domestic controllers, cultivates engineers familiar with domestic equipment, and promotes the widespread application of domestic instruments across industry, academia, and research.
Yudian stated that it will continue to drive technological innovation, participate in industry standard setting and teaching practices, promote more proprietary products into university classrooms, and jointly build an ecosystem for industry-education collaboration and talent cultivation.
The Yudian AI-888 digital controller has been rated as "internationally advanced" by authoritative experts from Tsinghua University and the Chinese Academy of Sciences, and is widely used in high-end manufacturing sectors such as semiconductors, photovoltaics, and lithium batteries. With a measurement accuracy of Class 0.1, it meets precision control needs across various industries. Equipped with a new APID self-tuning adaptive control algorithm, it achieves precise control without overshoot or undershoot under complex conditions such as large lag and external disturbances. Features include cascade control, AAT advanced fast self-tuning, 50-segment program control, heating and cooling dual output, bumpless manual/automatic switching, external event input, and multi-point input correction. It supports Yudian's AIbus and standard Modbus communication protocols, and can be converted to TCP, EtherCAT, and other communication methods via a communication controller for integration with intelligent manufacturing systems.
Founded in 1991, Xiamen Yudian Automation Technology Co., Ltd. is a national-level key "Little Giant" enterprise specializing in new and distinctive technologies, a national high-tech enterprise, and a leading domestic enterprise in temperature control instruments and industrial automation measurement and control. It is the main drafter of the national standard for industrial temperature controllers. The company's industrial scale in the temperature controller niche ranks among the top globally, with products covering hundreds of industries including semiconductors, photovoltaics, lithium batteries, biomedicine, and high-end materials. Yudian products are renowned for low temperature drift, high anti-interference, long lifespan, and low failure rates. Its self-developed high-end temperature controllers focus on high performance and reliability, making them the preferred choice for domestic semiconductor equipment leaders to replace imported products, and they have been successfully used in batch in front-end core semiconductor equipment with extremely stringent reliability requirements. The general-purpose multifunctional series temperature controllers hold over 70% market share in core photovoltaic equipment, and are the only domestic temperature controllers included in the selection catalogs of all leading lithium battery companies, with over half of smart temperature controllers in the lithium battery industry choosing the Yudian brand. Yudian temperature controllers are also applied in heat treatment, high-end materials, mechanical equipment, biomedicine, environmental protection, chemicals, and aerospace. As the chairman unit of the Display Control Instruments branch of the China Instrument and Control Society, Yudian has led and participated in the formulation of over 50 national/industry standards, obtained certifications including CE, UL, TÜV, RoHS, and ISO14001, and sells products to more than 150 countries and regions worldwide.
