Overview
Temperature Damping controls the amount of damping that will be applied to the line
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.
Tips
• A high damping value makes the process variable appear smoother because the reported value
changes slowly.
