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.
