← ScienceWhich outcome occurs when an unshielded capacitive sensor experiences excessive electromagnetic interference?
A)Spurious triggering of the sensor✓
B)Increased linearity of the output
C)Reduced sensitivity to target stimuli
D)Improved signal-to-noise characteristics
💡 Explanation
Spurious triggering occurs because **electromagnetic induction** introduces unwanted charge variations within the unshielded capacitance, crossing the detection threshold; therefore the sensor triggers randomly, rather than reliably representing the measured variable under normal electrical operating conditions.
