How to Measuring the Temperature of the PXI-1045 Controllers Using LabVIEW

0044 · ‎03-27-2008

Hi,

I need to continuously monitor the temperature of the PXI-1045 controller. I have had a look the vi supplied by NI on http://zone.ni.com/devzone/cda/epd/p/id/4538#0requirements which is developed for PXI-8196/95 and the PXI-8186/87 controllers. Can similar temperature measurement be done on PXI-1045?

Hi Mehran,

The tutorial you mentioned is for PXI controllers. The temperature that you measure is the CPU temperature on the controller. The 1045 is a PXI chassis - just the metal box that the controller and modules fit into. If you want to measure the temperature of the chassis itself, you'll need to attach a thermocouple (or similar) to measure it. If you want to measure the CPU temperature of the controller inside your 1045 chassis, that will depend on the controller you are using.

I hope this makes sense!

Thanks Tom,

I am more clear now. The NI controllers I am using are:

PXI-4060 - Digital Multimeter

PX!- 4461 - Dynamic Signal Analyzer

PXI-2586 - General-Purpose Relay

PXI-GPIB

Is it possible to measure the CPU temperature of any of these controllers inside my 1045 chassis?

Hi Mehran,

Sorry, but those aren't controllers either! Controllers are the 2- and 3-slot cards that act like the computer in your PXI system. They will generally have a model number of 81xx. For information on our PXI controllers, have a look at http://sine.ni.com/nips/cds/view/p/lang/en/nid/1534. When you measure the temperature of your PXI controller, you're measuring the temperature on the CPU - this is something you can do on almost any PC.

Chassis and PXI devices do not have CPUs with thermistors to measure the temperature, so you can't read the temperature. Again, if you want to determine the ambient chassis temperature you'll need to use a thermocouple or something similar.

Hi there,

I have the same question, but I do know the PXI controller I'm using, it's a PXI - 8106, so how can I programmatically get the controller's temperature in LabVIEW 8.5 ?

Also, same question for the DAQ board, I saw that MAX can show the current temperature of each board (I have a PXI 6254 and a PXI 6733) so it must be possible to get the temperaure of each DAQmx device in LabVIEW... so How ?

Thanks for any help

[FYI] I cross posted this question to LAVA Forums.

NI System monitor allows PXI diagnostic, see here.

Thanks goes to NevilleD for the link.
