The deviation from straight line (DSL) error is the maximum error (in mm) in the sensor
gap reading at a given voltage compared to a 4.0 mV per micrometer best fit straight line.
DLS errors are associated with errors in axial position or sensor gap readings.
The incremental scale factor (ISF) error is the maximum amount the scale factor varies
from 4.0 mV per micrometer when measured at specified increments throughout the
linear range. Measurements are taken at 500 µm increments. The ISF error is associated
with errors in radial vibration readings.
Basis of the data are measurements with:
•
EZ116x cable at the temperature of the AMS EZ 1000 Converter.
•
First meter of the EZ116x cable at the temperature of the EZ116x 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.
