A pressure transducer (PT) for monitoring the supply pressure at RICH's N2 panel has been wired to the N2 cRIO.

Attached is a diagram of RICH's N2 panel showing the PT's location in the lower, right corner of the diagram.

A connector was installed on the PT's wiring to allow the cabling to the cRIO to be disconnected in the event the gas panel needs to be moved. The PT is powered by the cRIO chassis' 5 V power supply and is read by the N2 cRIO module 5, channel 2. This channel had to be reconfigured in LabVIEW as as current input channel.

Presently, the transducer is measuring the pressure at the panel input to be ~ 21 psi. 

The panel pressure can be monitored in EPICS with the PV B_DET_RICH_INTLK_N2_PANEL_PR1.
