Tunnel Engineering Near-Infrared Moisture Sensor Underground Mixing Station Aggregate Moisture Content Equipment
The device emits near-infrared light in the characteristic absorption band of water molecules to irradiate flowing sand and gravel materials. By collecting the reflected spectral signals from the materials and combining a dedicated aggregate algorithm with a temperature compensation model, it performs high-speed calculations to output precise moisture content values. Throughout the process, no sampling is required and there is no contact with the materials, truly enabling uninterrupted non-destructive testing on the production line.
