Model A601-2A/2B High-precision Platform Tiltmeter
The model A601-2 Platform mount tiltmeter is designed 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, and high-accuracy tilt monitoring applications worldwide.
Model A603 High Precision Platform-Mount Tiltmeter
The model 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, and high-accuracy tilt monitoring applications worldwide.
