Emerson MMI-20019043 Manuel D’Utilisation

Added Damping

 is not applied if the mA output is fixed (for example, during loop testing) or if the mA

output is reporting a fault. Added Damping is applied while sensor simulation is active.

Set Added Damping to the desired value.

The default value is 0.0 seconds.

When you specify a value for Added Damping, the transmitter automatically rounds the value
down to the nearest valid value.

Added Damping

 values are affected by the setting of Update Rate and 100 Hz Variable.

When mA Output Process Variable is set to a flow variable, density, or temperature, Added
Damping

 interacts with Flow Damping, Density Damping, or Temperature Damping. If multiple

damping parameters are applicable, the effect of damping the process variable is
calculated first, and the added damping calculation is applied to the result of that
calculation.

Configuration:

•

Flow Damping

 = 1 second

•

mA Output Process Variable

 = Mass Flow Rate

•

Added Damping

 = 2 seconds
