A.3.3 Power supply
Load limitations
Maximum loop resistance is determined by the voltage level of the
external power supply, as described by:
Max. Loop Resistance = 43.5 (Power Supply Voltage – 10.5) ohms

Communication requires a minimum loop resistance of 250 ohms.
A.3.4 Temperature limits
Ambient
0 to 185 °F (-18 to 85 °C)
with meter option:
0 to 175 °F (-18 to 80 °C)
(1)(2)(3)
Process
0 to 250 °F (-18 to 121 °C) coplanar flange
0 to 300 °F (-18 to 149 °C) traditional flange
Storage
0 to 212 °F (-18 to 100 °C)
with meter option:
0 to 185 °F (-18 to 85 °C)
1. Process temperatures above 185 °F (85 °C) require derating the ambient tem-
perature limits by 1.5 °F per degree above 185 °F.
2. 220 °F (104 °C) limit in vacuum service; 130 °F (54 °C) for pressures below 0.5
psia
3. EPR O-ring is limited to 150 °F (66 °C) process temperature.
