Specifications and Reference Data
1-5 Vdc HART low power (output code M)
Output
Three wire 1–5 Vdc output, user-selectable for linear or
square root output. Digital process variable superimposed
on voltage signal, available to any host conforming to the
HART protocol.
2051
Digital communications based on HART Revision 5
protocol.
2051 with selectable HART
The 2051 with Selectable HART comes with Selectable
HART Revisions. Digital communications based on HART
Revision 5 (default) or Revision 7 (option code HR7)
protocol can be selected. The HART revision can be
switched in the field using any HART based configuration
tool or the optional local operator interface (LOI).
LOI
The LOI utilizes a 2 button menu with internal and external
configuration buttons. Internal buttons are always
configured for Local Operator Interface. External Buttons
can be configured for either LOI, (option code M4), Analog
zero and span (option code D4) or Digital Zero Trim
(option code DZ). See 2051 with Selectable HART product
manual (00809-0100-4107) for LOI configuration menu.
Power supply
External power supply required. Standard transmitter
operates on 9 to 28 Vdc with no load.
Power consumption
3.0 mA, 27–84 mW
Output load
100 k or greater (meter input impedance)
Turn-on time
Performance within specifications less than 2.0 seconds
after power is applied to the transmitter.
Overpressure limits
Transmitters withstand the following limits without damage:
2051CF flowmeters
 Ranges 2–5: 3626 psig (250 bar)
4500 psig (310,3 bar) for option code P9
 Range 1: 2000 psig (137,9 bar)
Static pressure limit
 Operates within specifications between static line pressures
of -14.2 psig (0.034 bar) and 3626 psig (250 bar)
 Range 1: 0.5 psia to 2000 psig (34 mbar and 137,9 bar)
Burst pressure limits
2051CF
10000 psig (689,5 bar)
Temperature limits
Remote mount transmitter temperature limits
At atmospheric pressures and above.
Humidity limits
0–100% relative humidity
Volumetric displacement
Less than 0.005 in.

)
Damping
Analog output response to a step input change is
user-selectable from 0 to 25.6 seconds for one time constant.
This software damping is in addition to sensor module
response time.
For 2051CFA Temperature Limits, see page 161.
