500 Self-Leveling Borehole Tiltmeter (Lily)

The Self-Leveling Borehole Tiltmeter is designed for volcanic and tectonic research, ocean bottom applications, and for monitoring of hydraulic fracturing and other subsurface processes in the mining and petroleum industries.

The tilt meter's high-pressure stainless steel housing is rated for submergence to depths of 3500 meters. You can attain even greater depths by switching to a titanium housing.

The tilt sensors can self-level on command through a range of ±10 degrees and have 5 nanoradians resolution over a dynamic range of ±330 microradians. The self-leveling feature keeps this tilt meter on scale indefinitely at the high gains required for geophysical work.

Its versatile RS232 and RS422 serial outputs, and its powerful firmware command set, give you a wide range of measurement and recording options. Data can be stored internally for periodic downloading, or streamed to your external network or recorder. GPS compatible output formats are included.

Suitable applications

• Volcanic and tectonic research
• Hydraulic fracture mapping
• Micro-deformation monitoring
• Deep ocean geophysics

RoHS certified version upon request (extended delivery time).
