KLD802 80G FM Radar Level Sensor
Introduction
What does FMCW stand for?
·FMCW, namely Frequency Modulated Continuous Wave.
·FMCW technology and pulse radar technology are two technologies used in high-precision radar ranging. The basic principle is that the transmitted wave is a high-frequency continuous wave. Its frequency changes with time according to the law of triangle wave.
FMCW (Frequency Modulated Continuous Wave), the received echo frequency and the transmitted frequency change law are the same, both are triangular waves. There is only a time difference. Using this tiny time difference, the target distance can be calculated.
FM continuous wave radar refers to a continuous wave radar whose transmitting frequency is modulated by a specific signal.
The principle of frequency modulated continuous wave (FMCW) radar is to send a continuous signal with a certain bandwidth and linear change in frequency, and then perform fast Fourier transform on the received continuous signal.
The time difference between the two signals is calculated by the frequency difference between the sending and receiving signals. Finally, like the pulse wave radar level meter, the corresponding distance value is obtained from the time difference.
FMCW radar can obtain very high accuracy, and its accuracy mainly depends on the linearity and temperature drift of the voltage controlled oscillator.
Feature
· Launch angle
Radar wave emission angle 3°. Even in extremely complex installation environment, it can measure the material level stably and accurately.
· Measuring range
The measurement range of the terahertz FM radar level meter is 0.1m-100m. It has a very small blind area and a large measurement range. It can meet most measurement occasions.
· Penetration
The terahertz frequency-modulated continuous wave radar level gauge is extremely penetrating. According to the dielectric constant of the crystalline medium, it can penetrate the crystalline layer of up to 100mm.

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.
