KLD802 80G FM Radar Level Sensor
Introduction
Level in the focus
KLD802 operates with a transmission frequency of 80 GHz. With an 80-mm antenna, this results in a beam angle of only 3°. The radar sensor receives only distinct, definitive reflections from the product surface. This makes the measurement more accurate and reliable.
Previous radar sensors required process fittings with a minimum size of 1½" to achieve adequate signal focusing. For that reason it was virtually impossible to use radar sensors on very small containers with their typically small mounting sockets. KLD802 operates with a transmission frequency of 80 GHz. This corresponds to a factor of 3 compared to the technologies used until now. For that reason, the antenna system and the process fitting can have correspondingly smaller dimensions.
Feature
- Non-contact measurement with FMCW working principle;
- The beam angle is small and it is more easier for the instrument to avoid interferencefrom a possible obstacle;
- The radar's antenna size is small, and it is easy to be installed;The upper dead zone is smaller, it is more suitable for the River Water Monitoring;

Installation
1.Flange Installation
When using flange installation, the minimum distance between the instrument and the tank wall should be 200mm.
① datum plane
② vessel center or axis of symmetry
2.Hoisting Installation
Installation Requirements
When installing the instrument, avoid installing it above the material inlet, and try to avoid various objects that affect the signal, such as stirring paddles, etc.
Under extremely complex working conditions, the instrument can work normally if there is no obstacle in the area with a radius of 20cm centered on the installation point.
Installation connection diagram:
The maximum installation spool height H max depends on the installation spool diameter D and the size of the product launch angle.
Too long installation connection will affect the radar performance.
