Overview
Viscosity Damping controls the amount of damping that will be applied to the line viscosity
value. It affects both dynamic viscosity and kinematic viscosity 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
Viscosity damping affects all process variables that are calculated from line viscosity.
Procedure
Set Viscosity Damping to the value you want to use.
The default value is 0.8 seconds. The range is 0 to 60 seconds.
Interaction between Viscosity Damping and Added Damping
When the mA output is configured to report either dynamic viscosity or kinematic
viscosity, both Viscosity Damping and Added Damping are applied to the reported viscosity
value.
Viscosity Damping controls the rate of change in the value of the process variable in
transmitter memory. Added Damping controls the rate of change reported via the mA
output.
If mA Output Process Variable is set to Dynamic Viscosity or Kinematic Viscosity, and both Viscosity
Damping and Added Damping are set to non-zero values, viscosity damping is applied first,
and the added damping calculation is applied to the result of the first calculation. This
value is reported over the mA output.
