1. Process temperatures above 185 °F (85 °C) require derating the ambient limits by a 1.5:1 ratio. For example, for process temperature of 195 °F (91 °C), new ambient
temperature limit is equal to 170 °F (77 °C). This can be determined as follows: (195 °F - 185 °F)3 1.5 = 15 °F, 185 °F - 15 °F = 170 °F.
2. 220 °F (104 °C) limit in vacuum service; 130 °F (54 °C) for pressures below 0.5 psia.
3. Not available with Rosemount 3051SAM_ _A.
4. 160 °F (71 °C) limit in vacuum service.
