A603 High Precision Platform-Mount Tiltmeter

Including two switchable gains and two low-pass filter settings.


A603 High Precision Platform-Mount Tiltmeter

The A603 Platform-Mount Tiltmeter is designed to fill the gap left by the obsoleted 520M. Units come with the same leveling worm-gear feet that were on the 520M.

The A603 also includes two switchable gains and two low-pass filter settings. Using an absolute gravity referenced electrolytic sensor, the A603 delivers ultra-high sensitivity to <2.5 nrad with virtually zero long-term drift. Output is a stable ±8 DC voltage (±16 VDC differential).

Rugged, reliable, and extremely accurate, the A603 is the preferred choice for:

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

RoHS certified version upon request (extended delivery time).
