has been used recently to supplement the bridge health monitoring [18-21], due to the high resolution of the commercial tiltmeter
up to 0.001 degree.

All digital zenith cameras share basically the same construction principles--they consist of optical tube with imaging device (usually a CCD assembly) on a mount, equipped with precision tiltmeter
(preferably biaxial), which can be rotated around vertical axis.
Although the swelling is too subtle for scientists like Kauahikaua to see, they can measure the slight changes with a tool called a tiltmeter
. This device works like a carpenter's level to measure tilting in Earth's surface.
State-of-the-art equipment includes four seismic sensing stations on the volcano's flanks and a "tiltmeter
" to detect minute alterations in the slope of the volcano, which swells when magma rises into it.
However, the Treatment Well Tiltmeter
Instrument, developed by a team from the two companies headed by Eric Davis, allows drillers for the first time to measure the height and width of a well in near real-time.
This is a model of a tiltmeter
, an instrument used by scientists to help predict volcanic eruptions.
Boring is scheduled to start later this month, and each observatory will contain a strain gauge, two seismometers, a tiltmeter
and a temperature sensor.
By 2008 the effects recorded in the azimuth 328.600 (03-04 WT tiltmeter
) were stronger than the results recorded in the azimuth 58.600 (01-02 WT tiltmeter
The boxes incorporate a tiltmeter
, a radio microcontroller and a board above that for the sensor, which could be anything from temperature sensors to strain gauges and load cells.
