Subject: N2 pneumatic pressure watch set up 

We have 2 transduser PX303-3KG5V   http://www.omega.com/pressure/pdf/PX303.pdf They  will be installed on the out put of the N2 cylinders to read the supply pressure.

I will order one DC power supply  http://www.omega.com/pptst/PSU93_FPW15.html      PSU-93

One full cylinder pressure is ~ 2400 PSI max so two of them will give us ~9Vdc

The email reminder should be send at 1000 PSI  =  1.8 V
