What does X mean in the instrument?
Thread Content
There is a gauge on the pump marked as * P15211A; I would like to know what the * symbol means Also, what do ZR and ZS mean?
It’s difficult to give a specific answer as there isn’t anything concrete, but we often use * to represent the pump’s operation signal; by inputting a DI to DCS ZR and ZS, it probably indicates run or stop
What you’re saying is too vague to answer; however, I think it should be about measuring vibration and displacement.
*It refers to the indicator signal of the pump (X denotes the pump and other equipment, while I stands for indicator). ZR should be the operation signal (Z represents position, and R stands for RUN, meaning operation), while ZS should be the stop signal (S stands for STOP, meaning cessation of operation)
X represents the displacement of the pump shaft. ZR should be the operation signal (Z stands for position, R stands for RUN), while ZS should be the stop signal (S stands for STOP)
X represents mechanical quantity, I represents indication, Z represents status, R represents operation, S represents stop
X represents mechanical quantity, I represents indication, Z represents status, R represents operation, S represents stop
I’m not sure if this is nonsense, but in control instrument diagrams: X denotes a pump; O stands for remote start, C for remote stop, R for restart, S for variable frequency control, A indicates the operating status, and B refers to current, while C represents over-rotation protection.
X represents mechanical quantity, I represents indication, Z represents status, R represents operation, S represents stop
