Rosemount 3051N

FUNCTIONAL

SPECIFICATIONS

Service	Liquid, gas, or vapor
Output	4–20 mA, user-selectable for linear or square root output; digital signal based
	on HART® protocol
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

	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 temperature 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.
