Dual axis analog inclinometer
±16 µradians | Model 520
Applied Geomechanics Incorporated
Our top performer for surface applications, Model 520 is designed for projects demanding maximum resolution and stability. Applications include leveling and alignment of platforms and antennae, measurement of earth tides and crustal deformation, and volcano monitoring. With resolution finer than 10 nanoradians, Model 520 is excellent for use in all static tilt applications, or as a sensitive long-period accelerometer. Each system includes the tiltmeter, a rugged fiberglass switch box and a 3-meter interconnect cable. Select among three gains and two low-pass Butterworth filters using switches in the switch box. Leveling and user calibration of the tiltmeter are performed with built-in micrometers or worm gear legs. Mechanical adjustment range is ±3 degrees.
