Additional Information
| Features | • ±14.5°, ±30° and ±90° ranges |
|---|---|
| Applications | • Platform Leveling/Positioning |
This geotechnical MEMS tiltmeter is available in uniaxial and biaxial configurations. It presents a robust and rugged design for outdoor geotechnical use, but with the benefit of low-cost MEMS technology and ±5VDC, 0-5 VDC, or 4-20 mA output signals. It is an effective tilt sensing solution for platform leveling/positioning, structural monitoring, construction monitoring, industrial machinery positioning, radial gate measurement & control.
