Temperature Coefficient
Temperature coefficient is calculated as the worst case shift over temperature. Temperature
coefficient is also presented as a percentage of Full Range. A system with a full range of 20 mils
(0.5mm) would have system with a temperature coefficient of
± 0.02%FR/
o
C or about
0.004mils/ o C (0.1 µ m/ o C). Typically the temperature coefficient of a KD5100 is the worst when
at the extremes of the range and is excellent at the null position because the sensors are balanced.
This tech note is referring only to the temperature coefficient of the sensors and does not include
the electronics temperature coefficient, which will be affected by the relative sensitivity.
