SL-2000D RF admittance level controllerDetailed product description：

The SL-2000D RF admittance level controller is developed based on the introduction of RF capacitor technology. Because all materials have different dielectric constants and their conductivity is different from that of air. A radio frequency is applied to a probe, and the probe and the container wall form a capacitor. When the probe comes into contact with the medium, the total impedance reflected by it changes due to the displacement of a small amount of electricity. This change is detected by the circuit and continuously analyzed (compared with the reference benchmark established by the sensitivity setting circuit in advance) to determine the changes in the surrounding environment (level).

The correct sensitivity setting will affect the output accuracy of the sensor. The special circuit design of the probe can enable the measurement circuit to automatically correct the accumulation of materials on the probe, thereby accurately reflecting the actual level of the material rather than sticking to the probe and accumulating materials.
