Before performing other transmitter on-line operations, review the digital
output parameters to ensure that the transmitter is operating properly and is
configured to the appropriate process variables.
The process variables for the 3051S provide transmitter output, and are
continuously updated. The pressure reading in both engineering units and
1, 1
percent of range will continue to track with pressures outside of the defined
3, 2
range from the lower to the upper range limit of the SuperModule.
Field Communicator v3.3
The process variable menu displays the following process variables:
• Pressure
• Percent of range
• Analog output
• Module temperature
• Scaled Variable (SV)
• Primary Variable (PV)
NOTE
Regardless of the range points, the 3051S will measure and report all
readings within the digital limits of the sensor. For example, if the 4 and 20 mA
points are set to 0 and 10 inH
25 inH O, it digitally outputs the 25 inH
2
reading. However, there may be up to ±5.0% error associated with output
outside of the range points.
AMS v7.0
Right click on the device and select "Process Variables..." from the menu.The
process variable screen displays the following process variables:
• Pressure
• Percent of range
• Analog output
• Module temperature
• Scaled Variable (SV)
• Primary Variable (PV)
The 3051S contains a temperature sensor near the pressure sensor in the
SuperModule. When reading this temperature, keep in mind the sensor is not
1, 1, 4
a process temperature reading.
