I wonder if it's the right time of year for the GDC to consider a 2014 rule allowing any pressure sensor rated for the pressure in the system at that point of installation. (If it would replace the switch, it would have to be rated against all failures; if it would supplement the switch, non-operation is not important, so it would need only be rated not to be pneumatically compromised in normal service.)
