← TechnologyWhich risk increases when a differential pressure sensor measuring filter blockage in a hydraulic servo loses calibration?
A)Unstable robotic arm trajectory✓
B)Increased PLC processing latency
C)Encoder resolution degradation
D)Compromised fluid bulk modulus
💡 Explanation
Losing calibration gives false filter status, causing reduced servo valve flow because the closed-loop feedback incorrectly compensates based on presumed blockage using proportional control principles, therefore unstable arm motion rather than stable motion occurs, rather than PLC delay.
