Level switch Float switch Sensor Application introduction of cement industry
Accurate and reliable process measurements are critical to the continued efficient operation of cement plants. Proper application of the most suitable field devices is the key to the success of all automation projects. Many gauges, sensors and continuous weighing equipment that can be installed in general processing plants are not suitable for the harsh environment encountered in the cement industry. Especially when it comes to high temperature and dusty environments, it is widely believed that there are some of the most difficult level measurement applications in the 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 use of alternative fuels poses new challenges for measurement. This article looks at the proper application, use, and maintenance of typical field devices and demonstrates by providing concrete examples from the cement industry. The paper also looks at the future trends of smart sensors and wireless communications that the cement industry may benefit from. Reliable operation of field devices is critical to any process control system. The typical cement plant environment presents many challenges, especially in areas filled with dust or high temperatures. To provide the best measurement capabilities and interface to plant control systems, instrument suppliers must focus on the specific needs and trends of the cement industry. Object Focus Measurement Due to the need for long-distance sensing and the presence of dusty and high temperature environments, it is difficult to perform efficient and reliable level measurement in cement plants.
