SPRING SENSITIVE ELEMENT OF GRAVIMETER Russian patent published in 2024 - IPC G01V7/00 

FIELD: measuring equipment.

SUBSTANCE: spring sensitive element of gravimeter, including electroconductive bowstring, which is connected to the middle working plate of the three-plate capacitor of the capacitive system for picking up the spatial position of this plate, a working metal spring of the sensitive element, a thermostat, a temperature compensator based on an internal thermoelectric sensor. Bowstring is made of tungsten threads, metal elastic bow-string tensioner and bimetallic temperature compensator are additionally included in the sensitive element, wherein the metal bowstring is fixed between the beams of the bow-tensioner, which is attached to the lower wall of the thermostat by means of a small-sized nut-bolt joint through the electrically conductive bracket and the first ceramic plate connected to each other, wherein the electric external output of the capacitor is connected to the electrically conductive bracket, and the working spring is attached to the upper wall of the thermostat through a bimetallic thermal compensator and a second ceramic plate.

EFFECT: high accuracy of measurements, strength at mechanical shocks, repairability, as well as providing the possibility of organizing large-scale production of SE.
