This application is level measurement in sandstone silo. The key of the solution is to apply 120GHz FMCW radar level transmitter, which has very narrow beam angle (<1°) , strong penetration and fast response. In the field, real-time monitoring of fast changing level is required.

Key points: sandstone, fast change of level, high accuracy

This is a typical application of sandstone silo. Sandstone is one of material for construction. With the improvement of quarry cutting machines , the demand for sandstone has increased, and governance has been becoming more and more important nowadays. 

ANL-9127, 120GHz FMCW THz radar level transmitter, is the first 120GHz radar around the world. The sandstone level measurement faces major problems: the range is too large to make easier in debugging or installing. ANL-9127's unique lens antenna and internal structure make the range up to 150m(in experiment between mountains can reach 500m). Secondly, the level of sandstone changes fast, so the response speed of equipment should keep faster to ensure the reliability of its value. ANL-9127, the beam angle is less than 1 ° to receive echo so fast , and the accuracy can be as high as 1mm in that get accurate values.

For traditional debugging method of large silo, back to the top of silo agian to check or dignose the setting increased the risk for users and engineers. ANL-9127 integrates Bluetooth wireless connection, which provides a way to help engineers and users to manage measurement on sites via cell phone.

  • Easy installation and maintenance free
  • 120GHz provides better accuracy
  • Reliable measurement for fast level change of solids
