A601-2 High-precision Platform-Mount Tiltmeter

The A601-2 Platform Mount Tiltmeter is suited for high precision tilt measurements. Units come with built-in micrometer leveling legs, for easy installation on any horizontal surface. The A601-2 also includes two switchable gains and two low-pass filter settings.

Using an absolute gravity referenced electrolytic sensor, the A601-2 delivers ultra-high sensitivity to <25 nrad with virtually zero long-term drift. Output is a stable ±8 DC voltage (±16 VDC differential).

Rugged, reliable, and extremely accurate, the A601-2 is the preferred choice for:

  • Volcano monitoring
  • High-precision geotechnical engineering
  • Bridge deflection monitoring
  • Precision metrology
  • Radar platform leveling
  • High-accuracy tilt monitoring applications

Available configurations

  • Model A601-2A (High Gain)
  • Model A601-2B (Mid Range)

RoHS certified version upon request (extended delivery time).
