Guided-Wave Rader Level Measurement
- Application:Solid material, Strong dust, easy to crystallize, condensation occasion
- Process Pressure:-0.1 ~ 0.1MPa
- Measuring Range:70M
- Radar Level Sensors
Radar sensors, by contrast, work not with sound waves, but with electromagnetic waves. This is the key difference between ultrasonic and radar sensors. Like the waves from ultrasonic sensors, the waves emitted from the radar sensor bounce off of objects and travel at a known speed (much faster than ultrasonic waves). Unlike ultrasonic sound waves, radar’s electromagnetic waves react differently to certain materials as they are reflected off the surface Radar level meter have high frequency radar sensor, the maximum measurement range is up to 70 meters. The instrumentation can be used for reactor solid silo and very complex measurement environment .,
Radar level transmitter antenna microwave pulse is narrow, the downward transmission antenna. Microwave exposure to the medium surface is reflected back again by the antenna system receives, sends the signal to the electronic circuit automatically converted into level signals.
♦ Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
♦ Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and
♦ Serious dust environment on the high level meter work has little effect.
♦ A shorter wavelength, the reflection of solid surface inclination is better.
♦ The measuring range is smaller, for a measurement will yield good results.
♦ High signal-to-noise ratio, the level fluctuation state can obtain better performance.
♦ High frequency, measurement of solid and low dielectric constant of the best choice
