[Dsg-rich] [New Logentry] Differential pressure transducers added to RICH N2 bubblers

Two differential pressure transducers have been connected to RICH's N2 bubbler.

One pressure transducer measures the pressure differential pressure between RICH's N2 volume and RICH's Electronic Panel. The transducer is read by RICHCRIO in the channel corresponding to Module 7, AI1.

The second pressure transducer measures the pressure differential between RICH's N2 volume and the external atmosphere. The transducer is read by RICHCRIO in the channel corresponding to Module 7, AI2.

The code to convert the raw current output from the transducers to a pressure value has not yet been added to the hardware interlock program. DSG will update the program to display the differential pressures in the LabVIEW user interface and also in EPICS.

The cRIO's interlock override switch has been turned off. The cRIO is running as normal and will disable of HV/LV if an interlock trips.
