Pressure sensor: You're required to have QTY 1 Nason P/N: SM-2B-115R/443 on the robot, installed per R77. If you have other pressure sensors, reference R66 to determine legality, and bear in mind that they are not the required one for running the compressor. Incidentally, you ought to be able to rig something up for the drivers' station to display what that required sensor is trying to tell you.

Regulator: Reference R64, R66G, and R71. If it fits those rules, you're good. Otherwise, your inspector will be helping you find a regulator that does.

Also note that gauges are required upstream and downstream of the primary regulator--displaying pressure on the driver's station will not take the place of those.
