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
