Damping Adjustment
The con
fi
guration menu 7 “DAMPING” allows
adjusting the damping of the output signal
according the application conditions. It is
important to make the difference between
the damping, the time constant and the
response time.
The damping corresponds to an average
value on the output signal for a pressure
input who changes very quickly program-
mable over a certain period of time called
damping value in sec.
The time constant
τ
is a
fi
xed value related
to the measuring upper range limit of a
transmitter
The response time corresponds to the time
that the output signal takes to reach around
62.3% when a pressure is applied corres-
ponding 0 to 100% of span. The response
time takes in account the time constant and
the dead time of the transmitter.
