This application is level measurement in PVC powder. The key of the solution is to apply 120GHz FMCW radar, which has narrow beam angle to reach strong penetration and no fear of dusty environment. It also can apply in small dielectric constant.

Key points: PVC powder, small dielectric constant, heavy dust

This is a typical application of PVC powder. PVC powder is one of the hardest measurement applications. The PVC powder's DK value is very small. Plus the dusts generated during process, the measurement is a tough work to do.

Thanks to ANL-9127, 120GHz FMCW THz radar level transmitter, the world's first 120GHz radar level transmitter, this problem is solved. It is based on advanced FMCW (Frequency-Modulated-Continuous-Wave) technology. It can reach 1° beam angle, and delivers good sensitivity and accuracy. It offers higher bandwidth. These advantages make measurement much easier, more accurate, more stable and environmental adapatablity,no matter of solid or liquid. Dust or sticky environment does not interfere with radar level transmitter's detection.

  • Accurate measurement with small dielectric constant
  • Unaffected by dusty environment and buildup onto antenna 
  • Easy installation and maintenance free
  • Unaffected by obstacles presented inside the PVC powder silo
