3 Theory of Operation
3.1 Constitution
Model ELT-10 Tiltmeter consists of tilt transducer, installation framework, signal transmission cable, etc.
3.2 Mechanism
The tilt deformation generated from the structure is transferred to the tilt transduced via the installation framework. In the transducer there are electrolyte and the conductive contact. When there is tilt, the liquid level of the electrolyte will be kept as horizontal. But the conductive contact relative to the level is changed so that the output electricity value is changed.
3.3 Calculation
The tilt angle θ and the output electricity value F have the following relationship when the measured structure has the tilted deformation:
θ=a + b×F + c×F2 + d×F3
Herewith,
θ: the tilted angle of the measured structure with the unit of °;
F: Real-time measured electricity value with the unit of F;
a, b, c, d: Calibration coefficients of the tiltmeter. |
