In an experiment, I want to control the change of the pressure of one Teledyne Isco Syringe pump B, according to the read pressure of another pump A.
Pump A is set by step increasing constant flow mode manually.
For example, if the pressure of pump A 10 MPa, pump B should be changed to the pressure of 12 MPa; if the pressure of pump A 10.5 MPa, pump B be changed to the pressure of 12.5 MPa.
Can I realize this function through Labview?
Any suggestion? Thank you!
In short, yes you can do this assuming you can both write to and read the pressure of Pump A. I am not sure how you communicate with the instrument (GPIB, DAQ etc..) but in short all you would need to do is wire the output of the read pressure of pump A to pump B but with whatever correction you want to put (in this case P(A) + 0.5 = P(B). Though I would also wire in a range, such as if Pump A exceeds a threshold don't have pump B do so and ruin both of your pumps/account for a signal error. The program would be incredibly simple to write. I've included a version of the program but since I don't know what kind of signalling you use I labelled the Pump A output as "Data From Pump A" and I labelled the input to pump B as input for Pump B. I use some logic to make sure the pressure isn't over a value (I just used 150 as a random number). Hope this helps.
Dear Tyler, thank you very much for the answer.
I have no experience of Labview programming and pump operation yet, and I don't know the details of the communication way now.
Your answer makes me believe that the function is realizable. This is the first step. Hereafter, I will start to learn how to modify the exist Labview program.
Maybe I will ask your help again several days later.
Thank you very much!
Best,
Johnny
Hi Johny,
If you are interested in turn key solution for your problem, I will be more than happy to help you to achieve your goals fast, and allow to integrate your experiment and automate data gathering.
Michal, it is kind of you to offer me the help.
Now I am out of office.
May I contact you several days later?
Thank you!
