Abstract. Wideband gradiometer instrumentation system based on the usage of "Cavendish balance" type torsion system allowing real-time registration of ultra low frequency (<10-2 Hz) disturbances of the terrestrial gravitational field has been considered. The principle of torsion system rotation angle measurement using position-sensitive detector as well as electronic circuits of the instrumentation system have been described. Examples of the instrument readings have been presented.
