Introduction
1.4 Transmitter overview
The Rosemount 2051C Coplanar design is offered for Differential Pressure (DP) and Gage
Pressure (GP) measurements. The Rosemount 2051C utilizes capacitance sensor technology for
DP and GP measurements. The Rosemount 2051T utilizes piezoresistive sensor technology for
AP and GP measurements.
The major components of the Rosemount 2051 are the sensor module and the electronics
housing. The sensor module contains the oil filled sensor system (isolating diaphragms, oil fill
system, and sensor) and the sensor electronics. The sensor electronics are installed within the
sensor module and include a temperature sensor, a memory module, and the analog to digital
signal converter (A/D converter). The electrical signals from the sensor module are transmitted
to the output electronics in the electronics housing. The electronics housing contains the
output electronics board, the optional external configuration buttons, and the terminal block.
The basic block diagram of the Rosemount 2051CD is illustrated in Figure 1-3 on page 5.
For the Rosemount 2051, pressure is applied to the isolating diaphragm(s). The oil deflects the
sensor which then changes its capacitance or voltage signal. This signal is then changed to a
digital signal by the Signal Processing. The microprocessor then takes the signals from the
Signal Processing and calculates the correct output of the transmitter. This signal is then sent to
the D/A converter, which converts the signal back to the analog signal, then superimposes the
HART signal on the 4-20 mA output.
An optional LCD can be ordered that connects directly to the interface board which maintains
direct access to the signal terminals. The display indicates output and abbreviated diagnostic
messages. A glass display cover is provided. For 4-20 mA HART output, the LCD Display features
a two-line display. The first line displays the actual measured value, the second line of six
characters displays the engineering units. The LCD can also display diagnostic messages.
Note
LCD Display utilizes a 5x6 character display and can display output and diagnostic messages. The
LOI Display uses an 8x6 character display and can display output, diagnostic messages, and LOI
menu screens. The LOI Display comes with 2 buttons mounted on the front of the display board.

Emerson Process Management Instrument and Valve Response Center representatives will
explain the additional information and procedures necessary to return goods exposed to
hazardous substances.
1.6 Product recycling/ disposal
Recycling of equipment and packaging should be taken into consideration and disposed of in
accordance with local and national legislation/regulations.
Individuals who handle products exposed to a hazardous substance can avoid injury if they
are informed of and understand the hazard. The product being returned will require a copy
of the required Material Safety Data Sheet (MSDS) for each substance must be included
with the returned goods.

2.3 System readiness
If using HART based control or asset management systems, confirm the HART
capability of such systems prior to commissioning and installation. Not all systems are
capable of communicating with HART revision 7 devices.
For instructions on how to change the HART revision of your transmitter, see
“Switching HART Revision” on page 80.
2.3.1 Confirm correct Device Driver
Verify the latest Device Driver (DD/DTM) is loaded on your systems to ensure proper communi-
cations.
1. Download the latest DD at www.emersonprocess.com or www.hartcomm.org.
2. In the Browse by Member dropdown menu, select Rosemount business unit of Emerson
Process Management.
3. Select desired Product
a. Within Table 2-1, use the HART Universal Revision and Device Revision numbers to find
the correct Device Driver
Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please review
the approvals section of the Rosemount 2051 reference manual for any restrictions
associated with a safe installation.
Before connecting a Field Communicator in an explosive atmosphere, ensure the
instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
In an explosion-proof/flameproof installation, do not remove the transmitter covers
when power is applied to the unit.
Process leaks may cause harm or result in death.
Install and tighten process connectors before applying pressure.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads
can cause electrical shock.

2.4 Configuration basics
The Rosemount 2051 can be configured either before or after installation. Configuring the
transmitter on the bench using either a Field Communicator, AMS Device Manager, or Local
Operator Interface (LOI) ensures all transmitter components are in working order prior to
installation. Verify that the security switch is set in the unlock position ( ) in order to proceed
with configuration. See Figure 4-2 on page 59 for switch location.
2.4.1 Configuring on the bench
To configure on the bench, required equipment includes a power supply, and a Field
Communicator, AMS Device Manager, or an LOI (option M4). Wire equipment as shown in
Figure 2-1 below. To ensure successful HART communication, a resistance of at least 250 s
must be present between the transmitter and the power supply, see “Power supply for 4-20 mA
HART” on page 63 for details. Connect the Field Communicator leads to the terminals labeled
“COMM” on the terminal block or 1-5V configuration, wire as shown in Figure 2-1 on page 10.
The Field communicator is connected to the terminals labeled VOUT/COMM.
