Hydronix examines how relative measurement values improve automation in bulk solids processing by offering high repeatability without the time-consuming complexities of traditional sensor calibration. Optimising Moisture Management in Bulk Solids Modern industrial processing relies on automation to maintain consistent quality. While moisture is a critical variable in production, manual testing is often too slow for real-time control. Inline sensors provide the necessary responsiveness, but the choice between absolute and relative values dictates the efficiency of the system. Differentiating Absolute and Relative Values Absolute moisture measurement represents the literal percentage of water in a material, requiring extensive laboratory testing and precise calibration. In contrast, relative values focus on the stability and repeatability of the sensor signal. This approach allows a controller to react to whether a material is wetter or drier than a set target. The Advantage of Repeatable Control Loops For automated processes like material conditioning or drying, absolute values are less critical than consistent feedback. A repeatable relative measurement allows

The moisture content of grain is crucial for the milling process. This article describes how moisture content can be controlled to achieve benefits in terms of quality, environmental sustainability and profitability of the final product. Introduction Grain is a natural product, so the moisture in the bulk material varies due to several factors, including different growing conditions, weather conditions during harvest, the threshing operation, and post-harvest storage conditions. After harvest, industrially processed grain is often handled in a mill where it is flaked, rolled or ground into flour. Moisture levels are a critical factor throughout the mill because they affect machinery performance, material plasticity or malleability, and final product quality. Also, achieving the correct moisture content of the final product is important to prevent premature spoilage and a short shelf life. By measuring and controlling the water content of the material at each step of the milling process, it is possible to improve efficiency, reduce energy consumption, and save money. Consistent moisture control also enables a miller to achieve higher yields of better quality with less waste. The main process measurement

Moisture sensors determine the moisture content, but there are other parameters that can be measured with near infrared light (NIR). The name MoistTech is self-explanatory that the moisture sensors detect moisture content, but there are so many more substances that absorb near infrared (NIR) light. Coating weight, protein and temperature are just a few measurables that can be detected with MoistTech’s line of products for quality control. How does NIR work? NIR technology works when different substances absorb NIR light at specific wavelengths. After analyzing the amount of NIR light absorbed in a sample, the machine can provide in-depth information about the substance being measured. In the case of MoistTech, it is a popular tool for industries that need to control moisture content in products, such as paper and food production. What does NIR measure? Moisture is far from the only entity NIR can measure. It can also detect levels of coating weight, sheet and film thickness, oil, protein and temperature, among others. NIR technology can be used in many industries including food, agriculture,
