Geotechnical tiltmeter for underwater applications

ETLG Inertial Aerosystems announce the model 820 Shallow Water series in their electrolytic tiltmeter line, designed for geophysical and geotechnical applications.

Manufactured by US based Jewell Instruments, this waterproof tilt solution provides civil engineers with a cost-effective and practical alternative to tiltmeters rated for fully waterproof use.

The 820 Shallow Water series is rated to 200 meters (656.2 ft) in depth and uses highly sensitive electrolytic technology to measure in one or two axes with a resolution to 0.0001° and virtually no long-term drift. Standard measuring ranges include ±0.5°, ±3° and ±50° with custom ranges available upon request. Analog, current and digital (RS232 and RS422) output options are available.

This tiltmeter is intended to monitor structural activity at relatively shallow depths such as bridges, dams, dry docks or any other partially submerged structure.
