THE SCA103T DIFFERENTIAL INCLINOMETER SERIES

Murata Manufacturing 

SCA103T Series

The calculated compensation curve can be used to compensate for the temperature dependency of

the SCA103T sensitivity by using following equation:

SENScomp  SENS *(1 Scorr /100)

Where:

SENScomp temperature compensated sensitivity

SENS

Nominal sensitivity (16V/g SCA103T-D04, 8V/g SCA103T-D05)

The typical sensitivity temperature dependency after 3rd order compensation is shown in the figure

below.

2 Functional Description

2.1 Differential Measurement

The measuring axis of SCA103T sensing elements are mutually opposite in direction, thus

providing two inclination signals which can be differentiated externally, either by using a differential

amplifier or a microcontroller.

The differential measurement principle removes all common mode measurement errors. Most of

the error sources have similar effects on both sensing elements. These errors are removed from

measurement result during signal differentiation. The differential measurement principle gives very

efficient noise reduction, improved long term stability and extremely low temperature dependency.
