Catalog excerpts

Floor-mount & Wall-mount Tiltmeter 14 The model A711-2 (floor-mount), and A716-2 (wall- mount) 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 Jewell Instruments LLC 850 Perimeter Road, Manchester, NH 03103
