Overview
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 reported process variable. At the end of the interval, the reported process variable
will reflect 63% of the change in the actual measured value. Added Damping controls the
amount of damping that will be applied to the mA output. It affects the reporting of mA
Output Process Variable through the mA output only. It does not affect the reporting of that
process variable via any other method (e.g., the frequency output or digital
communications), or the value of the process variable used in calculations.
Configuration and Use Manual
mA Output Process Variable = Mass Flow Rate
Frequency Output Process Variable = Mass Flow Rate
AO Cutoff = 10 g/sec
Mass Flow Cutoff = 15 g/sec
mA Output Process Variable = Mass Flow Rate
Frequency Output Process Variable = Mass Flow Rate
AO Cutoff = 15 g/sec
Mass Flow Cutoff = 10 g/sec
If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
- The mA output will report zero flow.
- The frequency output will report the actual flow rate.
If the mass flow rate drops below 10 g/sec, both outputs will report zero flow.
