illustrates 3051 transmitter data flow. Data flow can be summarized in
four major steps:
1.
A change in pressure is measured by a change in the sensor output (Sensor Signal).
2.
The sensor signal is converted to a digital format that is understood by the
microprocessor (Analog-to-Digital Signal Conversion). Sensor trim functions affect this
value. Select these options to alter the digital signal on the LCD or Field Communicator.
3.
Corrections are performed in the microprocessor to obtain a digital representation of
the process input (Digital PV).
4.
The Digital PV is converted to an analog value (Digital-to-Analog Signal Conversion).
Rerange and Analog trim functions affect this value. Select these options to change the
range points (4-20 mA or 1-5 Vdc).
For a summary of recommended calibration procedures, refer to
. Also,
identifies the approximate transmitter location for each calibration task.
Data flows from left to right and a parameter change affects all values to the right of the
changed parameter.
