Murata Manufacturing SCA100T
THE SCA100T DUAL AXIS INCLINOMETER SERIES The SCA100T Series is a 3D-MEMS-based dual axis inclinometer family that provides instrumentation grade performance for leveling applications. The measuring axes of the sensing elements are parallel to the mounting plane and orthogonal to each other. The Murata inclinometers are unsensitive to vibration, due to their over damped sensing elements, and can withstand mechanical shocks of up to 20000 g.FEATURES
