Indication
Optional 5-digit LCD display
Overpressure limits
Rosemount 3051CF
 Range 0: 750 psi (51,7 bar)
 Range 1: 2000 psig (137,9 bar)
 Ranges 2–5: 3626 psig (250 bar)
4500 psig (310,3 bar) for option code P9
Static pressure limit
Operates within specifications between static line pressures
of 0.5 psia and 3626 psig.
Range 1: 0.5 psia and 2000 psig (3, 4 bar and 137, 9 bar)
Burst pressure limits
Burst pressure on Coplanar process flange is 10000 psig
(69 MPa).
Failure mode alarm
Output code A
If self-diagnostics detect a gross transmitter failure, the
analog signal will be driven either below 3.75 mA or to
21.75 mA to alert the user. NAMUR-compliant values are
available, option code C4. High or low alarm signal is
user-selectable by internal jumper.
Output code M
If self-diagnostics detect a gross transmitter failure, the
analog signal will be driven either below 0.94 V or above
5.4 V to alert the user (below 0.75 V or above 4.4 V for
Option C2). High or low alarm signal is user-selectable by
internal jumper.
Output code F and W
If self-diagnostics detect a gross transmitter failure, that
information gets passed as a status along with the process
variable.
Process temperature limits
For 3051CFA Temperature Limits, see page 161.
Humidity limits
0–100% relative humidity
Turn-on time
Performance within specifications less than 2.0 seconds
(10.0 s for Profibus protocol) after power is applied to the
transmitter
Volumetric displacement
Less than 0.005 in.

Damping
Analog output response to a step input change is
user-selectable from 0 to 36 seconds for one time
constant. This software damping is in addition to sensor
module response time.

1. Process temperatures above 185 °F (85 °C) require derating the
ambient limits by a 1.5:1 ratio (0.6:1 ratio for the 3051H).
