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.

长期基础静水力水平的长期研究结果

摘要

本文介绍了使用静压水准仪（HL）的测量结果，该静压水准仪安装在IPE RAS预后中心的前提下，设计用于在1 km的线性基准上进行约10 m的测量。在新的电容式换能器的操作上获得了实验数据，该电容式换能器具有更大的动态范围，并且对液位的垂直位移具有0.1μm的灵敏度。膨胀容器已经过测试；测量HL时间常数为110 s；并给出了三​​个月观测值的频谱分析。提出了一种新的HL方案，该方案包括用于补偿温度变化影响的体积，这是构造该设备的长基础版本所必需的。
