[Hallb-engineering] [New Logentry] Pressure Transducers on Cryo Systems

Great care must be taken in design of cryogenic pressure transducer installation. Nearly every PT or DP in both CLAS12 Torus and Solenoid needed to have a damper put in to give actual process pressures vs an oscillating pressure caused by pumping (thermo-acoustic) oscillations causing neraly continuous swings in the signals.

I will be giving a cryo lessons learned talk on these magnets some time in the next few months. For those who are designing PT / DP hardware now please see me.
