A NOVEL EMFC TILTMETER WITH EXTENDED MEASUREMENT RANGE

Abstract:
This work presents a new tiltmeter that utilises the principle of electromagnetic force compensation (EMFC) in order to increase its measurement range and measurement dynamics compared to an uncompensated pendulum tiltmeter. The development included investigations on the design of the pendulum mechanics, the position sensor and the actuators. With the chosen parameters a resolution of 1 µrad in a measurement range of 20 mrad can be achieved currently on a short-term timescale.
