NI USB-6009

[walberg]

I have some lm35 and the NI usb6009

I have connected 0 volt to 32  +5 to 31  and signal tot  2 (analog)

Is there a Vi i can use to read the temperature (i even don't know with function to take to display the voltage. (i have used a meter)

How must i configure the 6009 to read the temperature (i think i must use voltage) 

I even want to use the signal to compare with a parameter (temperature)  and when this signal is reached (by example 250 mv  (25 grad celcius) i want to trigger a digital output. (I have crydom sensitive (5ma) solid state relays).

Dear Walberg,

thank you so much for your post on our webforum. I noticed some pictures to connect this sensor to a USB 6008 /6009 device. You can use an external power supply, but if you connecting the sensor to the 5V pin balast resistors (120k - 200k) are reccomended.

If I undersant correct the scale is linear so then the easiest way is to measure in voltage and multiply your measurements with 100.

Best regards,
