Ni-USB-6009 digital imput for Monarch optical sensor

[uwe038]

I am trying to input diagital data from Monarch optical sensor to NI-USB-6009 DAQ.

So far I am only able to see True or False from signalexpress after connecting the optical sensor, how can I make it show RPM?

Here is the manual of the therometer: http://www.monarchinstrument.com/pdfs/1071-4849-110R_ROLS24-W.pdf

Thanks

Could you specify on which pins you are connecting your optical sensor?

I am connecting signal input to PFI 0 which is the counter now.

What I understand from the operating instructions of your optical sensor, it outputs a TRUE value every time the object does a revolution. So by measuring the amount of times it outputs a TRUE value in one minute you will be able to determine the RPM. On signal express you will only be able to see the signal but not the RPM value. If you want to do that I would recommend to create a LV VI that can detect the change of values of your sensor and then count the amount of time the sensor outputs a TRUE value. That way you can compute the RPM.

It seems the only way can make it work.

I have tried counter port on the DAQ PFI, it was able to read the counting up of number, and that is all it could do.

I am thinking to buy an individual display for the optical sensor, which can help me to make my life easier instead of getting into world of Labview.

Thanks for your replies Inachosa!

Sure you are welcome. If you find that easier go for it!
