What accounts for the response-delay of EHI nozzles using solenoid actuators compared with those using piezo actuators?
A) solenoids require higher voltage
B) piezo stacks draw more current
C) piezo actuators open nozzles without having to move themselves
D) solenoids must build and collapse magnetic fields before mechanical movement occurs

Question

Quizplus · Accepted Answer

Solenoids require time to build and collapse magnetic fields before they can initiate mechanical movement, leading to a response delay compared to piezo actuators, which can act more directly and quickly.
