Hi Yuki!
LabVIEW 7 Express is a discontinued version of LabVIEW, it was released all the way back in 2003. To adquire the data from those sensors I would recommed that (if possible) you get a more updated version of both LabVIEW and DAQmx.
If you're willing to continue with your current software, you would need first a version of Traditional DAQmx compatible with LabVIEW 7 Express. You can see the list here:

After that, you would need to acquire some DAQ hardware compatible with those drivers. You can see the compatible hardware for Traditional DAQmx 7.5 here:

Take in consideration that the SCB-100 is a a connector block, it is not designed to acquire data, which means that you need to get a different piece of hardware.
For further reference you can find the user manual for LabVIEW 7 Express:

I hope it helps.
