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.
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 down to the nearest valid value.
4.3.3 Configure Temperature Input
Temperature data from the on-board temperature sensor (RTD) is always available. You
can set up an external temperature device and use external temperature data if you want
to.
• Configure Temperature Input using ProLink III
• Configure Temperature Input using the Field Communicator
