A601-2 Electrolytic Tiltmeter0 pages
Model A601-2A/2B High-precision Platform Tiltmeter
The model A601-2 Platform mount tiltmeter is our new
micrometer adjustment design 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.
