PCIe-6320 card does not recognize the signal from my instrument

[joel29]

Hi

I have connected a PCIe-6320 to a calorimeter via a SHC68-68 -EP cable. The software of the calorimeter is running on Windows 10. I can record the time  but not the temperature and the heat output (milliwatts) (Values are negative and zero, respectively, see attachement) . I think that the card does not recognize the equipment. Any idea on how to configurate the card please?

Thanks.

Hi Joel,

The PCIe-6320 is a multi-function I/O card so is capable of reading digital and analog voltage signals.

You can take a look at the datasheet for specific values on analog/digital ranges.

If your temperature and heat flow is in milliamps, then you will need to connect some external circuitry that will allow the PCIe-6320 to find the voltage from your current. It will not be able to read a current value directly.

By using a resistor of known value, you can calculate the voltage using Ohm's Law (V=IR), where "I" will be varying depending on the output from your calorimeter.

You can then read the voltage across the resistor with your PCIe-6320 card.

Hope this helps!

Thank you for your answer.

the calorimeter signal comes out as milliwatts.

the temperature signal should be volt I think.

I am not familiar in card configuration, so I think that I would need more information on how to configurate the card.

I do not want to add any more peripherical devices as I do not think that this would be possible.
