Inside the mechanical positioner: pneumatic amplifier, relay
Thread Content
What will happen if the output of the pneumatic amplifier is blocked, but the (input) signal remains? Will high-frequency vibrations cause abnormal noises?
No, aren’t these just the exhaust and intake passages?
If the amplifier is blocked, the actuator shouldn’t work~ Use a very thin wire to clear the amplifier. As for enabling the on/off function with vibration, it’s probably because the vertex value is too high; adjust the vertex value~
