SCA100T 双重的轴倾角罗盘系列 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. Low temperature
dependency, high resolution and low noise, together a with robust sensing element design, make the SCA100T the ideal choice for leveling
instruments. The VTI inclinometers are insensitive to vibration, due to their over damped sensing elements, and can withstand mechanical
shocks of up to 20000 g.
