Floor-mount & Wall-mount Tiltmeter

The model A711-2 (floor-mount), and A716-2 (wall­mount) bolt or clamp to any surface, and are well suited
for areas with heavy traffic or vibration. Electronic
performance is identical to the model A701-2. Units
include two switchable gains and two low-pass filter
settings, and are sensitive to <0.1 urad. Output is a
stable ±8 DC voltage (±16 VDC differential). Applications
include volcano monitoring, high-precision geotechnical
engineering, bridge deflection monitoring, precision
metrology, radar platform leveling, and high-accuracy
tilt monitoring applications where bolt-on installations
are required.
