Rosemount 3051N

PERFORMANCE SPECIFICATIONS

Reference Accuracy

Based upon zero-based calibrations, reference conditions, 4–20mA analog output, and digital trim values equal to the span setpoints

Includes hysteresis, terminal-based linearity, and repeatability(1)

Range Code	Ambient Temperature Effect per 50° F (28° C)

0± (0.25% URL + 0.05% span)

1± (0.1% URL + 0.25% span) from 1:1 to 30:1 RDF

± (0.14% URL + 0.15% span) from 30:1 to 50:1 RDF

2 – 5	± (0.0125% URL + 0.0625% span) from 1:1 to 5:1
	± (0.025% URL + 0.125% span) from 5:1 to 100:1

Rosemount 3051NA

Range Code		Ambient Temperature Effect per 50° F (28° C)

0		± (0.1% URL + 0.25% span)

1 –	4	± (0.025%	URL + 0.125% span) from 1:1 to 30:1
		± (0.035%	URL + 0.125% span) from 30:1 to 100:1

(1)RDF = Range Down Factor = URL / Calibrated Span

(2)Exposure of isolating diaphragms to process temperatures above 185 °F (85 °C), but below 250 °F (121 °C), produces a temperature effect of ±1.0% of calibrated span in addition to the effects listed.
