Rosemount 3051N

Calibration Overview

Complete calibration of the Rosemount 3051N Pressure Transmitter involves the following tasks:

Configure the Analog Output Parameters

•Set Process Variable Units (page 2-8)

•Set Output Type – Linear or Square Root (page 2-8)

•Set the Range Points (page 2-9)

•Set Damping (page 2-12)

Calibrate the Sensor

•Full Trim (page 2-18)

•Zero Trim (page 2-17)

Calibrate the 4–20 mA Output (Digital-to-Analog [D/A] Signal Conversion)

•4–20 mA Output Trim (page 2-19)or

•4–20 mA Output Trim Using Other Scale (page 2-19)

Figure 2-7illustrates the Rosemount 3051N transmitter data flow. This 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 can be understood by the microprocessor (Analog-to-Digital Signal Conversion).

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).

Figure 2-7also identifies the approximate transmitter location for each calibration task. Note that the data flows from left to right, and a parameter change affects all values to the right of the changed parameter.

Not all calibration procedures should be performed for each Rosemount 3051N transmitter. In addition, some procedures are appropriate for bench calibration but should not be performed during field calibration. Table 2-2identifies the recommended calibration procedures for each type of Rosemount 3051N transmitter for both bench and field calibration.
