Free Space Radar Level Transmitter


Tek-Wave 4300C Free Space Radar Level Transmitter is a 26GHz high-frequency radar type level measuring instrument measuring up to 90 feet. This high-frequency radar transmitter is the best choice for measuring solids and low dielectric constant medium. Easy to install with a horn that fits in a 2” NPT. The antenna is furthered optimized as the new fast microprocessor can carry out signal analysis and processing at a higher rate. Therefore, Tek-Wave 4300C Free Space Radar Level Transmitter can be used for complex measurement conditions. The 4300C is not affected by foam, changes in water vapor, temperature or pressure. Its shorter wavelength provides good reflections on sloping surfaces. The small beam angle and the energy is concentrated, enhancing the echo ability and avoiding interference. Smaller measurement blind areas help to achieve good results for small tank measurement.

  • East to install as small size antenna.
  • Non-contact radar without wear and pollution.
  • Hardly affected by corrosion, foam and changes in water vapor including temperature and pressure in the atmosphere.
  • Influence is minimal during serious dust environment.
  • Shorter wavelength.
  • Better reflection when inclined solid surface.
  • Small Beam angle and energy concentrated.
  • Enhance the echo ability and avoid interference.
  • Smaller measurement blind area.
  • High signal-to-noise ratio.
  • Can achieve better performance even in the case of fluctuation.
  • High frequency is the best choice for measuring solid and low dielectric constant medium.
