RF admittance level meter

Category: Level Meter

8001@huadianauto.com

Product Introduction:

The RF admittance level switch measures and controls the material level by sensing changes in the reactance (capacitive reactance and impedance) between the probe and the storage tank. Its internal electronic unit, the probe measurement electrode, and the reactance between the unloaded tank together form a balanced bridge circuit that generates a stable oscillation signal. When the measured medium covers the probe measurement electrode, it causes a change in the reactance between the probe electrode and the tank, leading to an imbalance in the bridge circuit and stopping the oscillation signal. The subsequent circuit detects this change and outputs an alarm signal.
