78 INTEGRATION_TIME R/W S U8 1 S
From 0.01 to 1.28 seconds
This parameter is available only for piezo-resistive
and capacitive sensor types
The Integration Time of the A/D converter can be changed
between 0.1s and 1.28s in steps of 0.01s. The accuracy of the
transmitter will be higher with a high Integration Time. The
transmitter will be faster with a short Integration Time but the
output will be more noisy depending on the process conditions.
The output will rise linear with 10ms cycle after a step of the
input value. The end value will be reached with expiration of the
Integration Time. The default value of the Integration Time is
0.3s for transmitters with ≥0.04% accuracy and 1.28s for trans-
mitter with 0.025% accuracy. The setting of the integration time
is independent from the Damping.
The Integration Time shall be set to 1.28s for the calibration of
the pressure measurement.
