Model 850 MEMS Tuff Tilt Sensors

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.
