Radar Level Transmitter is high-frequency level measurement instruments with the maximum measuring distance up to 70 meters. The antenna is further optimized, and the new-type microprocessor can perform higher rate of signal analysis and processing, making the instrument availablc for complex measurement conditions , such as reactors , solid silos.
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 ( because the microwave propagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost Instantaneous).
Feature：
1. Small antenna size , easy to install , Non-contact radar , no wear , no pollution.
2. Almost no corrosion , bubble effect , almost not affected by water vapor in the atmosphere , thetemperature and pressure changes.
3. Strong dust in the operation environment has little effect to the electromagnetic wave.
4. A shorter wavelength , the reflection of solid surface inclination is better.
5. Beam angle is small , the energy is concentrated , can enhance the ability of echo and to avoidnter ference.
6. The measuring range is smaller , for a measurement will yield good results.
7. High signal-to-nose ratio , the level fluctuation state can obtain better performance.
8. High frequency , measurement of solid and low dielectric constant of the best choice.
