An LCD (Liquid Crystal Display) is a flat screen that uses liquid crystal cells to display images. When sampling bulk materials in the food and feed industry, an LCD display can be used in various contexts:
Definition of LCD display:
An LCD display works with liquid crystals placed between two polarizing filters. By applying an electrical voltage to certain crystals, they can be aligned in such a way that light is either transmitted or blocked to produce images. LCDs are known for their low energy consumption, lightness, and ability to produce clear and sharp images.
Use in the sampling of bulk materials:
- Control & Monitoring: Many modern bulk sampling systems are equipped with an LCD display to provide operators with a visual interface to control and monitor the sampling process. The display can show information such as the status of the process, the selected settings, error messages and other relevant data.
- Quality Control: An LCD display can be used in analyzers that inspect samples directly in the field. It can display information about the composition, humidity, temperature or other factors relevant to the quality of the bulk material.
- Integration with other systems: LCD displays in sampling systems can often be integrated with other devices, such as computers or networks, to provide centralized control and monitoring.
- Ease of use: An intuitively designed LCD display makes it easy to operate the sampling system and can increase the efficiency and accuracy of sampling by visualizing complex processes.
- Data recording and retrieval: LCD displays also allow you to view recorded data, including lot number, date/time of sampling, quantities, and other important information necessary for traceability and quality assurance.
In summary, when sampling bulk solids, an LCD display is an important tool that serves to control, monitor and document the sampling process by providing a clear and efficient interface for the operator.
