CX-RLM-906S 26G high frequency radar - stainless steel flange level gauge
1. Millimeter-wave radar, with a measurement accuracy of up to ± 2mm and a minimum blind area of 0.05m. 2. Smaller antenna size to meet the measurement of more working conditions. 3. A variety of lens antennas, smaller emission angles, more concentrated energy, and stronger echo signals, so it has higher reliability than other radar products under the same industrial and mining conditions. 4. It has stronger penetrability and can be used normally under the condition of adhesion and condensation. 5. CX-RLM-F series products have larger dynamic signal range and more stable measurement for low dielectric constant media. 6. Multiple measurement modes, the radar response time is less than 1S in the fast measurement mode.
The general principle of frequency-modulated continuous wave radar level gauge: the radar emits electromagnetic waves on the top of the tank. The electromagnetic waves are received by the radar after being reflected by the medium. The frequency difference δf between the received signal and the transmitted signal is proportional to the distance R of the medium surface: R = C (speed) * δf (frequency difference) / 2 / K (frequency modulation slope). Since the speed of light C and the frequency-modulated slope K are known, the frequency difference δf is estimated, and the distance R of the surface of the radar installation position can be obtained. Then, the known space height of the tank is subtracted from the radar to the material surface. Empty height), the height of the material level is obtained.
