KLD802 Radar Liquid Level Senor 80GHz 4-20mA HART -non-corrosive liquid, slightly corrosive liquid

KLD Series 80GHz 4-20mA HART Radar Liquid Level Senor

Principle

KLD800 series 80G radar level gauge adopts frequency modulated continuous wave (FMCW) technology. The antenna emits a high-frequency FM radar signal, and the frequency of the radar signal increases linearly. The transmitted radar signal is received by the same antenna after being reflected by the measured medium. At the same time, the frequency difference between the transmitted signal frequency and the received signal frequency is proportional to the measured distance. The collected frequency difference signal is subjected to fast Fourier transform (FFT) to obtain the spectrum of the reflected echo, and the distance to the target to be measured is calculated based on this.

 Feature   

• Millimeter wave radar, the measurement accuracy can reach up to ±2mm, and the minimum measurement blind zone is 0.05m.
• The smaller antenna size satisfies the measurement of more working conditions.
• A variety of lens antennas, smaller launch angles, more concentrated energy, stronger echo signals, and higher reliability than other radar products under the same industrial and mining conditions.
• It has stronger penetration and can be used normally in the case of adhesion and condensation.
• The dynamic signal range is larger, and the measurement of low dielectric constant media is more stable.
• Multiple measurement modes, radar response in fast measurement mode
