Proper way to connect a solenoid

Not sure how much to spend on an analog pressure sensor, but we use these in industry. http://www.ifm.com/products/us/ds/PN2024.htm with good success.

I'm reading that spikes can only switch 12v, which is why I believe that it didn't work for us.

You mentioned earlier, and I'm reading here http://team358.org/files/pneumatic/ that 24v solenoids can be run through the cRIO power. Are you familiar with how this is done?
