A capacitive sensor excited with a high-frequency signal includes a guard ring to improve its performance. If the guard ring is removed, what is the most likely impact on sensor performance?

Question

Accepted Answer

The fringing effects would become more significant, potentially leading to non-linearity and reduced accuracy.

Answer

The sensor would become more immune to electromagnetic interference

Answer

The sensor's sensitivity would significantly increase

Answer

The capacitance might change unpredictably due to increased coupling to surrounding objects
