Measuring Temperature Using NI USB-6343

[scrider]

Hello All,

Has anyone ever measured temperature using a NI USB-6343 or something close to it? Ran into any issues?  

I was reading about the device and it was suggested that signal conditioning might be necessary and I am a little concerned...

Normally I use an Agilent DAQ but this specific project I am working on will require some unique timing and the USB-6343 handles a majority of my issues along will plenty of coding examples.

Scrider,

Connecting thermocouples directly to the 6343 will result in up to two additional junctions creating unwanted EMF voltages as there is no in-built CJC. You will have to calibrate for these manually and offset this via a constant within software or through signal conditioning.

Thanks Daniel,

Does NI have a multifunctional device that will allow for thermocouple reading as well?

Scrider,

Are you wanting a device that has USB connectivity just like the 6343? If so, we do have several USB based DAQ devices for thermocouples. The links below will show 3 devices we have:

Now I know some of these probably won't be ideal for your application, but I just wanted to give you options. It also depends on how fast you would like your sampling rate to be. These devices are specific for thermocouple use, but you can still use them (excluding the TC01) for voltage readings. Hope this helps!

How is purchasing another module a solution.  In the USB-6343 setup it allows thermocoupples. so why would I have to purchase another device.  I bought a 6343  to read 12 K-Type thermocoupplers.  WOuld adding another thermocouppler right at the tb help
