Model 701 Platform Tiltmeter Series


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 711-2 & A716-2


The models 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. Floor-mount models are available with a weatherproof NEMA 4X seal (A711-2 4X), or with an RS-232, RS-422, or RS-485 digital output (D711). D711 units also include onboard memory with a storage capacity of up to 22,000 samples. Units include two switchable gains and two low-pass filter settings and are sensitive to <0.1 µrad. 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.
