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.
