Abstract
The article describes the results of measurements using a hydrostatic level (HL) with a base of about 10 m, designed for measurements on a linear base of 1 km, installed in the premises of the prognostic center of IPE RAS. Experimental data are obtained on the operation of a new capacitive transducer with an increased dynamic range and 0.1-μm sensitivity to vertical displacement of the fluid level. The expansion vessel has been tested; the HL time constant has been measured, which is 110 s; and a spectral analysis of three months of observations is presented. A new HL scheme is proposed, which includes volumes to compensate for the influence of temperature changes, necessary for the construction of a long-base version of the device. The results of the studies bring us closer to implementing the scheme of a device with a linear base of 1 km in the adit of the TRINITY state scientific center.
