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 Murata
inclinometers are unsensitive to vibration, due to their over damped sensing elements, and can withstand
mechanical shocks of up to 20000 g.
Features
 Dual axis inclination measurement (X and Y)
 Measuring ranges ±30° SCA100T-D01 and
± 90° SCA100T-D02

 Sensing element controlled over damped
frequency response (-3dB 18Hz)
 Robust design, high shock durability (20000g)
 High stability over temperature and time
 Single +5 V supply
 Ratiometric analog voltage outputs
 Digital SPI inclination and temperature output
 Comprehensive failure detection features
o True self test by deflecting the sensing
elements’ proof mass by electrostatic force.
