| Abstract: | In this letter, a biaxial vertical pendulum tilt meter for measuring the micro-tilt of superficial coat of the earth in two directions is presented, Its basic structures and principles are also described. The sensitivity of the device was calibrated experimentally with a piezoelectric transducer （PZT）. Experimental results show that the biaxial vertical pendulum tiltmeter can measure two orthogonal direction tilt signal, so it verily reflect the tilt signal where a dot in earth. The tilt tides in two directions of EW （east and west） and SN （south and north） has been observed with hiaxial vertical pendulum tiltmeter and with a precision of 10^-9 rad. |
