Ultra-high sensitivity to <0.1 µrad with virtually zero long-term drift
High precision tilt measurements

701-2 Biaxial Platform Tiltmeter

The biaxial 701 Platform Tiltmeter is our most popular design for rapid installation and high precision. Using its built-in Invar leveling legs, it can be set up and operating on any hard horizontal surface within minutes. The two orthogonal tilt sensors parallel the sides of the base plate.

Each tiltmeter includes a temperature sensor. The internal electronics drive signals over cable lengths greater than 1000m. Model 701-2 has two switchable gains and two low-pass filter settings.

This tiltmeter is a popular choice for volcano monitoring, platform leveling, and measuring structural response to applied loads.

Available configurations
