Abstract

Изобретение относитс  к виброметрии. Цель изобретени  - повышение датчика и увеличение его чувствительности. Датчик содержит установленный с возможностью перемещени  в корпусе 1 элемент 2 per1 ти- ровани  зазора со севтоводом 3. В корпусе 1 установлены также плоские пружины 9, на которых подвешена инерционна  масса 10, состо ща  из трех частей. 2 ил.The invention relates to vibrometry. The purpose of the invention is to increase the sensor and increase its sensitivity. The sensor contains an element 2 that permits the movement of the gap with the seawater 3 mounted in the housing 1. In the housing 1 there are also mounted flat springs 9 on which an inertial mass 10 consisting of three parts is suspended. 2 Il.
