Effect Of Temperature Damping On Process Measurement; Configure Pressure Compensation - Emerson Micro Motion 1500 Configuration And Use Manual

Configure process measurement
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
Tip
Temperature Damping affects all process variables, compensations, and corrections that use
temperature data from the sensor.
Procedure
Enter the value you want to use for Temperature Damping.
The default value is 4.8 seconds. The range is 0.0 to 38.4 seconds.
Tips
• A high damping value makes the process variable appear smoother because the reported value
changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value
changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual
measurement because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
The value you enter is automatically rounded off to the nearest valid value. Valid values for
Temperature Damping are 0, 0.6, 1.2, 2.4, 4.8, ... 38.4.
4.6.3 Effect of Temperature Damping on process
measurement
Temperature Damping affects all processes and algorithms that use temperature data
from the internal sensor RTD.
Temperature compensation
Temperature compensation adjusts process measurement to compensate for the effect of
temperature on the sensor tubes.
4.7

Configure pressure compensation

Pressure compensation adjusts process measurement to compensate for the pressure
effect on the sensor. The pressure effect is the change in the sensor's sensitivity to flow
and density caused by the difference between the calibration pressure and the process
pressure.
