Temperature controller

[J_LA]

Hi,

I am new to Labview and have a project to complete. I need to controll the temperature of a chamber and need to display the readings of the present temperature through labview. The temperature controller is Lakeshore 331. Could anybody please help me out?

J_LA,

If you're new to LabVIEW then I would reccomend you check out our Getting Started with LabVIEW page. It has links to some free online LabVIEW training as well as links to our in classroom training.

There are a couple forum threads dealing with this exact issue, please check them out.

• Lakeshore mode 331 temperature controller
• Visa Issues with Lakeshore 311
• Labview control of LS331 using RS232 port

Also, here are a bunch of documents on Temperature Measurements with LabVIEW.

Hi everyone,

I am also new to labview with some basic knowledge. I have a project to do about Automatic Temperature Monitoring and Control System. Guide me and post some schematic diagram to simulate in labview. Thanks.

Hi,

You can find some examples at Labview >> Help >> Find examples >> Hardware Input and Output >> DAQmx >> Analog Input >> Thermocouple-Continues Input.vi.

I need an automatic control for example, the continuous sample input voltage is set and convert to equivalent temperature. The upper limit and lower limit of temperature is set and when excess, the automatic control of temperature will take place. Like this be possible? Guide and give links for diagrams. Thanks

M Aus,

Code for a tempertaure controller is going to depend a lot on your setup. Are you planning on using a PID controller? Do you just want to have a heater kick on when a temperature threshold is exceeded? What sort of hardware are you using? There are a lot of different options for a project like this.

I want a simple circuit, the temperature of the room is measure and add as input voltage from DAQ assistant continuously and thus voltage will convert to equivalent temperature and monitored. Then there will be lower and upper limits for the temperature and when exceeds these limit an automatic temperature will take plase. For example, when it becomes over 77 degree F, the temperature will be reduced and when be low 68 degree F, the temperature will adjust to up. I want a stable temperature between 68 to 77 degree F.

Best regards.

Sorry I need to add something. I want a pure labview program without hardware. Thank you.

What inputs and outputs do you have available to you? For instance, do you have a heater that you would like to turn off when a thermocouple reads over a certain temperature? What do you mean when you say that you do not want hardware?
