The Jewell Instruments A906 Little Dipper Inclinometer is an in-place inclinometer system for monitoring slopes, embankments, deep excavations, tunnels, tank foundations, retaining walls and other types of ground movement. Installed as a string of vertical or horizontal sensors inside inclinometer casing, or by direct burial, this instrument provides a continuous record of ground displacement.

Fiberglass rods connect the sensors inside the casing, and fins or universal pivots couple the sensors to the casing walls. Little Dipper's on-board electronics accept a wide input voltage range and drive long cables without signal loss. The waterproof and non-corrodible ABS sensor housing makes it suitable for underwater tilt measurements. Select analog voltage output (biaxial) or 4-20 mA output (uniaxial only). Features: detect movements smaller than 0.1 inch in 100 ft; standard version ±30° with 0.02° resolution; high gain version ±12° with 0.005° resolution; 0.15 second time constant; vertical or horizontal orientation.
