The incremental scale factor (ISF) error is the maximum amount the scale factor varies
from 16.0 mV per micrometer when measured at specified increments throughout the
linear range. Measurements are taken at 125 µm increments. The ISF error is associated
with errors in radial vibration readings.
Basis of the data are measurements with:
•
AMS EZ 1000 Converter and EZ190x at the temperature of the AMS EZ 1000 Converter.
•
First meter of the EZ105x cable at the temperature of the EZ105x tip.
•
No ambient temperature change of the AMS EZ 1000 Converter during 1 hour before
the measurement. Power and sensor connected to the AMS EZ 1000 Converter for at
least 10 minutes before measurement and calibration.
•
Emerson reference target material is 42CrMo4 (AISI 4140), unless otherwise stated.
Note
For measurements that require a higher measuring accuracy, factory calibrated measuring
chains are available.
Accuracy of measuring chains different from the standard measuring chain
Add the measurement inaccuracies in
accuracy of measuring chains different from the standard measuring chain. The
incremental scale factor (ISF) error is typically ±5%, this applies to 90% of the measuring
range.
