7.2.2 Configure Temperature Damping using ProLink III
ProLink III Device Tools → Configuration → Process Measurement → Sample Temperature → Temperature
Damping
Temperature Damping controls the amount of damping that will be applied to the sample temperature
value, when the on-board temperature data is used (RTD).
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 to 38.4 seconds.
Tip
• 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 to the nearest valid value. Valid values for Temperature
Damping are 0, 0.6, 1.2, 2.4, 4.8, … 38.4.
