SCA100T Series
The equation of fitted 2nd order polynome curve for sensitivity compensation is:
Scorr 0.00011*T 2 0.0022*T 0.0408
Where:
Scorr:
T
2nd order polynome fitted to average sensitivity temperature dependency curve
temperature in °C
The calculated compensation curve can be used to compensate the temperature dependency of
the SCA100T sensitivity by using following equation:
SENScomp SENS *(1 Scorr /100)
Where:
SENScomp temperature compensated sensitivity
SENS
Nominal sensitivity (4V/g SCA100T-D01, 2V/g SCA100T-D02)
The typical offset and sensitivity temperature dependency after external compensation is shown in
the pictures below.
