The model A711-2(4X) Weatherproof Floor-mount Tiltmeter offers the same performance as the model A701-2(4X), but in a floor-mount package. Units are rated IP65 waterproof for use in wet, humid, and corrosive environments. The A711-2(4X) bolts or clamps to any horizontal surface, and is well suited for areas of heavy traffic or vibration. Units deliver <1 ?radian resolution or better. Output is a stable ±8 DC voltage (±16 VDC differential), and the powerful internal electronics will drive cables over 1000m. Use this precision tiltmeter for volcano monitoring, geotechnical engineering, structural monitoring, platform leveling, and any application where advanced protection from weather is required.
