lProduct Overview of radar level sensor
This radar level sensor adopted 26G high frequency radar sensor, the maximum measurement range can reach up to 20 meters. Antenna is optimized further processing, the new fast microprocessors have higher speed and efficiency can be done signal analysis, the instrumentation can be used for reactor, solid silo and very complex measurement environment.
l Principle of radar level sensor
Radar level sensor 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 (because the microwave propagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost instantaneous).
l The characteristics of 26G radar level sensor:
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 pressure changes.
Serious dust environment on the high level meter work has little effect.
A shorter wavelength, the reflection of solid surface inclination is better.
Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
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.
