Title: Can someone calibrate a 20,000 Pnuematic pressure gauge?
Post by: USMCPMEL on 11-17-2017 -- 10:44:44
I saw this topic on a forum on Facebook and noticed no one said they could. I was just wondering if someone could calibrate this and if so how? What standards do you use?

I finally gave up and left all the pmel related Facebook groups. They typically turn into whine fests or "what's playing on little Jimmy's ipod today" type posts (no offense meant to anyone named Jimmy, coulda used Johnny or Jodie or Bob or [insert name here]).

Wika claims to be able to calibrate to 8000 bar.

We can do 16,000 on the DWT.  Able to do 150,000 dynamic pressure, but that's apples and oranges. 

No way in hell would I be anywhere near that pneumatic system at WIKA.

We can calibrate to 72,000 PSI with oil using DHI 50316 to ±20 PSI.

You could have if you own operate the test bench in the picture http://www.pmelforum.com/index.php?topic=4046.0 . The Ruska separator needed to perform the cross float could handle the rated pressures (both pneumatic and hydraulic) but since it appears that hydraulic fluid has made it to both sides of the diaphragm, you separator is now rated for fluid only. Unit is obsolete via Fluke and the rebuild kit is no longer available. I would bet someone has this setup still available. The Southwest Research Institute in San Antonio is close I believe. I do no see why the WIKA (Mensor) lab, if listed on their scope would not be able to handle... certain has to be taken for sure but that line of product appears to work as advertised.
