Which 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.
