Limit is flange rating or sensor rating, whichever is lower (see Table A-2). Table A-2. 2051L Flange Rating

Standard	Type	CS Rating	SST Rating
ANSI/ASME	Class 150	285 psig	275 psig
ANSI/ASME	Class 300	740 psig	720 psig
At 100 °F (38 °C), the rating decreases with
	increasing temperature.
DIN	PN 10–40	40 bar	40 bar
DIN	PN 10/16	16 bar	16 bar

At 248 °F (120 °C), the rating decreases

with increasing temperature.
