SCA103T Series
Data Sheet
THE SCA103T DIFFERENTIAL INCLINOMETER SERIES
The SCA103T Series is a 3D-MEMS-based single axis inclinometer family that uses the differential measurement
principle. The high calibration accuracy combines extremely low temperature dependency, high resolution and low
noise together with a robust sensing element design, to make the SCA103T an ideal choice for high accuracy
leveling instruments. The VTI inclinometers are insensitive to vibration due to having over damped sensing
elements plus they can withstand mechanical shocks of 20000 g.
Features
Measuring ranges ±15° SCA103T-D04 and
± 30° SCA103T-D05
0.001° resolution (10 Hz BW, analog output)
Sensing element controlled over damped
frequency response (-3dB 18Hz)
Robust design, high shock durability (20000g)
Excellent stability over temperature and time
Common mode error and noise reduction
using the differential measurement principle
Single +5 V supply
