we are building an automated testing oven. It has been decided that it's cheaper and more convenient to use a pre built PID controller, however
our task is to set the temperature of oven using LabView code, thus the PID should communicate with computer.
I would be really grateful if you could give me a piece of advice whether such controllers exist and where they can be found or it might be easier to use DAQ box + NI PID
toolkit + power transistor with external power supply + heating element.
P.S just to note, working temperature range is not very high ( 20 - 200C)
All the best
Solved! Go to Solution.
you should contact your local NI branch and ask for a visit of the sales rep.
He/she could give you some options and information you then can think about and select.
When you talk about PID controller, there are two options:
1. Software based PID controller (that you can develop using LabVIEW PID toolkit)
2. Hardware based PID controller... if you choose to have a hardware based PID, you need to make sure that it can be used with LabVIEW, I know that what your concern is...!!
Mostly these PID controllers (hardware based) are a serial instrument (RS-232, RS-485 or MODBUS based) and that can be easily integrated with LabVIEW.. no toolkit is required but all you need is VISA functions or MODBUS library.
I am not allergic to Kudos, in fact I love Kudos.
Make your LabVIEW experience more CONVENIENT.
Thanks very much! I'll have a look on these controllers, VISA functions are not a problem, used to work with them before, now have to decide on the right controller!
