2.4 Transmitter overview
The Rosemount 2051C Coplanar™ design is offered for Differential Pressure (DP) and
Gauge 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 transmitter are the sensor module and the electronics
housing. The sensor module contains the oil filled sensor system (isolating diaphragm, 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 transmitter
is illustrated in Figure 2-3.
When pressure is applied to the isolating diaphragm, 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 display 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
display can also display diagnostic messages.
Note
LCD display utilizes a 5 × 6 character display and can display output and diagnostic
messages. The LOI display uses an 8 × 6 character display and can display output,
diagnostic messages, and LOI menu screens. The LOI display comes with two buttons
mounted on the front of the display board. See Figure 2-2.

Rerange with an applied pressure source using local zero and span buttons
If ordered, local zero and span buttons (option code D4) can be used to rerange the
transmitter with an applied pressure. Refer to Figure 2-11 for analog zero and span button
location.
To rerange the transmitter using the span and zero buttons, perform the following
procedure:
Procedure
1. Loosen the screw holding the top tag of the transmitter housing. Rotate the label to
expose the zero and span buttons.
2. Confirm device has local zero and span buttons by verifying blue retainer under the
tag.
3. Apply transmitter pressure.
4. Rerange the transmitter.
a) To change the zero (4 mA/1 V point) while maintaining the span: press and
hold zero button for at least two seconds then release.
b) To change the span (20 mA/5 V point) while maintaining the zero point:
press and hold the span button for at least two seconds and then release.
Example
Note
4 mA and 20 mA points must maintain the minimum span.

Note
• If the transmitter security is on, adjustments to the zero and span will not be able to be
made. Refer to Configuring transmitter security for security information.
2.8.3
• The span is maintained when the 4 mA/1 V point is set. The span changes when the 20
mA 5 V point is set. If the lower range point is set to a value that causes the upper range
point to exceed the sensor limit, the upper range point is automatically set to the
sensor limit, and the span is adjusted accordingly.
• Regardless of the range points, the transmitter measure and report all readings within
the digital limits of the sensor. For example, if the 4 and 20 mA(1–5 Vdc) points are set
to 0 and 10 inH2O, and the transmitter detects a pressure of 25 inH2O, it digitally
outputs the 25 inH2O reading and a 250 percent of range reading.
Damping
The damping command changes the response time of the transmitter; higher values can
smooth variations in output readings caused by rapid input changes. Determine the
appropriate damping setting based on the necessary response time, signal stability, and
other requirements of the loop dynamics within your system. The damping command
utilizes floating point configuration allowing the user to input any damping value within
0.0–60.0 seconds.

2.10.1 Configuring alarm and saturation levels
26 Rosemount 2088, 2090P, and 2090F Pressure Transmitter Reference Manual
In normal operation, the transmitter will drive the output in response to pressure from the
lower to upper saturation points. If the pressure goes outside the sensor limits, or if the
output would be beyond the saturation points, the output will be limited to the associated
saturation point.
The transmitter automatically and continuously performs self-diagnostic routines. If the
self-diagnostic routines detect a failure, the transmitter drives the output to configured
alarm and value based on the position of the alarm switch. See Setting transmitter alarm.
Table 2-5: Rosemount Alarm and Saturation Values
Level 4–20 mA (1–5 Vdc) saturation 4–20 mA (1–5 Vdc alarm
Low 3.90 mA (0.97 V) ≤ 3.75 mA (0.95 V)
High 20.80 mA (5.20 V) ≥ 21.75 mA (5.40 V)

High 20.10 mA –22.90 mA (5.025 –5.725 V) 20.20 mA – 23.00 mA (5.05 –5.75 V)
Failure mode alarm and saturation levels can be configured using a Field Communicator,
AMS Device Manager, and the LOI. The following limitations exist for custom levels:
• Low alarm level must be less than the low saturation level
• High alarm level must be higher than the high saturation level
• Alarm and saturation levels must be separated by at least 0.1 mA (0.025 Vdc)
The configuration tool will provide an error message if the configuration rule is violated.
Note
Transmitters set to HART® multidrop mode send all saturation and alarm information
digitally; saturation and alarm conditions will not affect the analog output. See also
Establishing multidrop communication.

2.10.2 Configuring scaled variable
The Scaled Variable configuration allows the user to create a relationship/conversion
between the pressure units and user-defined/custom units. There are two use cases for
Scaled Variable. The first use case is to allow custom units to be displayed on the
transmitter's LCD/LOI display. The second use case is to allow custom units to drive the
transmitter's 4–20 mA (1–5 Vdc) output.
If the user desires custom units to drive the 4–20 mA (1–5 Vdc) output, Scaled Variable
must be re-mapped as the primary variable. Refer to Re-mapping device variables.
The Scaled Variable configuration defines the following items:
• Scaled Variable units - custom units to be displayed.
• Scaled data options - defines the transfer function for the application (linear and square
root)
• Pressure value position 1 - lower known value point with consideration of linear offset.
• Scaled Variable value position 1 - custom unit equivalent to the lower known value
point.
• Pressure value position 2 - upper known value point
• Scaled Variable value position 2 - custom unit equivalent to the upper known value
point
• Linear offset - the value required to zero out pressures effecting the desired pressure
reading.
• Low flow cutoff - point at which output is driven to zero to prevent problems caused by
process noise. It is highly recommended to use the low flow cutoff function in order to
have a stable output and avoid problems due to process noise at a low flow or no flow
condition. A low flow cutoff value that is practical for the flow element in the
application should be entered.

Re-mapping device variables
The re-mapping function allows the transmitter primary, secondary, tertiary, and
quaternary variables (PV, 2V, 3V, and 4V) to be configured as desired. The PV can be
remapped with a Field Communicator, AMS Device Manager, or a LOI. Variables (2V, 3V,
and 4V) can only be re-mapped via Field Communicator or AMS Device Manager.
Note
The variable assigned to the primary variable drives the 4–20 mA (1–5 Vdc) output. This
value can be selected as Pressure or Scaled Variable. The 2, 3, and 4 variables only apply if
HART® burst mode is being used.

Refer to Figure 2-16 for instructions to remap the primary variable using a LOI.
Figure 2-16: Re-mapping with LOI
If the transmitter is repaired or replaced, verify the transmitter alarm level before
returning the transmitter to service. This is useful in testing the reaction of the control
system to a transmitter in an alarm state. Thus ensuring the control system recognizes the
alarm when activated. To verify the transmitter alarm values, perform a loop test and set
the transmitter output to the alarm value see Configuring alarm and saturation levels.
Note
Before returning transmitter to service, verify security switch is set to the correct position.
Refer to Verify configuration.
