SCA61T Series
THE SCA61T INCLINOMETER SERIES
The SCA61T Series is a 3D-MEMS-based single axis inclinometer family that provides instrumentation grade
performance for leveling applications. Low temperature dependency, high resolution and low noise together with
robust sensing element design make the SCA61T 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
20000 g.
Features
• Measuring ranges ±30° SCA61T-FAHH1G
and ± 90° SCA61T-FA1H1G
• 0.0025° 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
• 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.
o Continuous sensing element interconnection
failure check.
o Continuous memory parity check.
• RoHS compliant
• Compatible with Pb-free reflow solder process
Applications
• Platform leveling and stabilization
• Leveling instruments
• Acceleration and motion measurement
