Model 701 Platform Tiltmeter Series
Highlights:
The Model 701-2 Platform mount tiltmeter is our most popular design for high precision tilt measurements. Units come with built-in invar leveling legs, for easy installation on any horizontal surface. The A701-2 also includes two switchable gains and two low-pass filter settings. Using an absolute gravity-referenced electrolytic sensor, the A701 delivers ultra-high sensitivity to <0.1 µrad with virtually zero long-term drift. The output is a stable ±8 DC voltage (±16 VDC differential). The D701 digital version has onboard memory, with a storage capacity of up to 22,000 samples.
Model A603 High Precision Platform-Mount Tiltmeter
Highlights:
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.
