KLD802 Radar Level Sensor With Non Contact PTFE Lens Antenna For Continuous Level Measurement

 KLD802 Maintenance-free Radar Level Sensor with Non-contact PTFE Lens Antenna for Continuous Level Measurement
 
Introduction
 
The 80G radar level sensor adopts frequency modulated continuous wave (FMCW) technology, and transmits a high frequency continuous frequency modulated radar signal through its antenna. The transmitted signal is reflected by the medium and received by the antenna as echoes with different frequencies. The change in frequency is proportional to the distance and converted to material level height.
 
KLD800 series 80G ultra-high frequency radar instrument uses a non-contact measurement method to measure the level of liquid and solid media. They measure a wide variety of liquid media, even at high pressures and extreme temperatures. Such as solvent measurement, corrosive medium measurement, hygienic measurement, etc. At the same time, it can also measure light and heavy solids stably and reliably. Even strong dust and noise, adhesion and condensation will not affect the measurement results.
 
Feature
 
1. Non-contact measurement.
The measurement will not be affected by changes in medium properties or process conditions, such as temperature, pressure or dust intensity. Adjusting settings is easy, eliminating the need for filling and emptying containers, saving time during instrument start-up, and making the instrument virtually maintenance-free.
 
2. Large measuring range and small blind area
The measurement range is 0.1~120m, which basically meets the measurement requirements of on-site working conditions.
 
3. The antenna size is small, the beam angle is small, and the focusing ability is strong
It is convenient for radar on-site installation. It has stronger anti-interference ability for the environment inside the tank. For example, there are stirring, heating coils, baffles, etc. in the tank or the measurement effect in the straight pipe is still good.
 
4. High precision
The accuracy can reach ±2mm, which can fully meet the accuracy requirements of non-metering field working conditions.
 
5. The signal wavelength is short
It is better for the measurement of the level of powder, particles and so on.

Radar level sensors can measure liquids, slurries and solids. The radar level sensors has pressure and temperature resistance, and will not be affected by the measurement medium during measurement, and has high measurement accuracy. In terms of installation, if it can be used and installed correctly, it will have a good measurement effect and ensure accurate data.
For the installation of radar level sensor, we should pay attention to two points:
One is to ensure the vertical incident material level after aiming at the target material level, and the other is to avoid false echoes.So when installing, we suggest:
 
1. The radar level gauge should be installed at least 20CM away from the container wall, preferably about 1/6 of the container diameter. Do not install the radar level gauge above the water inlet pipe and in the center of the container, otherwise there will be many false echoes, which will interfere with normal signal reception.
2. If the radar level gauge cannot maintain an appropriate distance from the container wall due to the relatively small diameter of the container or other reasons, false echoes will appear on the container wall and the radar level gauge when the distance is small, so the debugging It is necessary to store false echoes in order to avoid errors in the future.
3. If the installation container is concave or conical, you need to pay attention to the installation. When using it, the radar beam of the radar level gauge reaches the lowest point of the bottom of the tank. If the liquid level is lower than this point, it cannot be measured. The purpose of adjusting the lowest point is to ensure the accuracy of the measurement data.
