Accurate and reliable process measurement is crucial for continuous and efficient operation of cement factory. Proper application of the most suitable on-site equipment is the key to the success of all automation projects. Many instruments, sensors and continuous weighing equipment that can be installed in ordinary processing factory are not suitable for the harsh environment encountered by the cement industry, especially when it comes to high temperature and dusty environment as it is generally believed that there are some of the most difficult material position measurement applications in this industry that need to be addressed. The application of new technologies has resulted in better performance and reliability for some of the more problematic devices. In addition, the increasing popularity of alternative fuels poses new challenges to measurement. This part focuses on the proper application and maintenance of typical on-site equipment, and demonstrates it by specific examples from the cement industry. It also looks forward to the future trend of intelligent sensors and wireless communication that may benefit from the cement industry. Reliable operation of on-site equipment is crucial to any process control system. The environments of typical cement factory pose many challenges, especially in dusty or high-temperature areas. In order to provide the optimal measurement function and interface to the factory control system, instrument suppliers must focus on the specific needs and trends of the cement industry. Due to the need for long distance sensing and dusty and high temperature environment, it is difficult to carry out efficient and reliable material position measurement in cement factory.
