Emerson Rosemount 1195 - BASIC SETUP; Set Process Variable Units

5-7
Process Variables
The process variables for the ProPlate provide the flowmeter output,
and are continuously updated. The process variable menu displays the
following process variables:
• Flow Pressure
• Percent of Range
• Analog Output
• DP Pressure
• Sensor Temperature
The flow pressure reading in both Engineering Units and Percent of
Range will continue to track with pressures outside of the defined
range from the lower to the upper range limit of the sensor module.
(1)
Sensor Temperature
The ProPlate contains a temperature sensor just above its pressure
sensor in the sensor module. When reading this temperature, keep in
mind that this is not a process temperature reading.
BASIC SETUP Set Process Variable Units
The PV Unit command sets the process variable units to allow you to
monitor your process using the appropriate units of measure. Select
from the following engineering units:
HART Comm. 1, 2
(1) Previous versions of the software will track with pressure up to 105% of span, and
remain there as pressure increases.
HART Comm. 1, 1, 5
HART Comm. 1, 3
