The SLDL5526 dual‑cable guided wave radar level meter is a professional contact‑type level transmitter specially designed for measuring low dielectric constant liquids and solids. It is widely used for continuous level measurement in industrial tanks and silos, delivering stable and reliable readings even in harsh working conditions.
The SLDL5526 dual‑cable guided wave radar level meter works based on the time‑of‑flight principle. High‑frequency pulses emitted by the probe travel along the cable or rod at the speed of light. When the pulses hit the medium surface, they reflect back to the receiver. The instrument then converts the travel time into an accurate level signal for real‑time monitoring.
The SLDL5526 dual‑cable guided wave radar level meter uses an advanced microprocessor and unique echo processing technology. It supports multiple process connections and probe components, making it ideal for high temperature, high pressure, and low dielectric media environments.
The SLDL5526 dual‑cable guided wave radar level meter meets IP66/IP67 protection standards. The cable entry is well sealed to effectively prevent water and dust ingress, ensuring long‑term stable operation.
1.High‑precision compact contact sensor with stable performance
2. Ideal for powders and granules; unaffected by dust, filling noise, or air flow
3. Concentrated energy provides stronger anti‑interference and higher accuracy
4. Small antenna size for easy installation, suitable for small and special tanks
5. Small blind zone expands the effective measuring range
6. Short wavelength penetrates foam and heavy condensate for tough conditions
7. Ultra‑low emission power, safe for all vessels and environments
8. Stable signal even when the medium surface is fluctuating
9. Simple maintenance, cost‑effective, and wide application range
