Intrinsically safe 26 GHz radar material level sensor with 70 m range for solids and bulk materials in underground coal bunkers, compact cylindrical design.
The Intrinsically Safe Mining Material Level Sensor uses 26 GHz high-frequency radar measurement with intrinsically safe design and a maximum range of 70 m, mainly for solids and bulk materials. Its cylindrical form factor of approximately φ250 mm × 365 mm is designed with underground installation space and mining usage requirements fully considered.
Coal bunkers, silos and storage chambers underground hold bulk material whose level must be monitored for safe and efficient operation — too full and the conveyor backs up, too empty and production gaps appear. The Intrinsically Safe Mining Material Level Sensor measures these materials reliably using 26 GHz high-frequency radar, with intrinsically safe design and a maximum range of 70 m, mainly for solids and bulk materials.
High-frequency radar is well suited to dusty, misty and material-filled environments because radar waves penetrate dust and are not confused by the material surface. The 26 GHz frequency provides a good balance of penetration, reflection and beam concentration for mine bunker measurements. The sensor structure is designed with underground installation space fully considered: its cylindrical form factor is approximately φ250 mm × 365 mm, and the φ250 mm body size helps balance internal space for components with measurement performance.
Because the sensor is intrinsically safe, it can be installed over bunkers and silos in hazardous underground areas. It provides continuous, non-contact level data for coal and bulk materials, supporting automatic bunker management, conveyor coordination and accurate inventory tracking in the mine.
