Grain temperature monitoring is critical to managing the quality of grain in long term storage. Insect infestation and mold growth can occur and can be detected by looking for temperature increases or “hot spots” within the grain in storage. Aplus Finetek Sensor, Inc. provides quality monitoring system of grain temperature and level in silos to prevent spoilage and provide optimal grain storage quality as well as a holistic range of instrumentation to achieve a complete and effective automated production flow process control.
