TKWL-1100 Series 26GHz High-Frequency Radar Level Gauge

The TKWL-1100 Series 26GHz High-Frequency Radar Level Gauge outputs a 4-20 mA analog signal and can measure distances up to 70 m. The optimized antenna and fast microprocessor support high-speed signal analysis, making it suitable for complex measuring conditions such as reactors and solid material silos.

The radar antenna emits narrow microwave pulses that travel at the speed of light. When the pulse reaches the measured medium surface, part of the energy is reflected and received by the same antenna. The time interval between the transmitted and received pulses is used to calculate the distance to the medium surface.

  • Non-contact measurement without wear or contamination.
  • 26 GHz transmitting frequency with small antenna size.
  • Short wavelength for better reflection from inclined solid surfaces.
  • Little influence from water vapor, temperature and pressure changes.
  • Suitable for severe dust environments.
  • High signal-to-noise ratio for stable performance under fluctuating conditions.
