Microwave Level Switch

The microwave switch probe forms a high-frequency resonant circuit with the internal electronic unit, generating a high-frequency microwave electric field around the probe. When the probe is covered by material or the dielectric constant of the surrounding medium changes, the resonant frequency will produce an obvious shift. The internal electronic unit compares the real-time resonant frequency with the user preset alarm threshold to activate or cut off the alarm signal. This detection method can effectively eliminate false triggering interference caused by conductive material adhesion.
