THE METHOD & DEVICE MEASURING MINUTE PRSSURE BY MANOMETER AND RAY FIBER

摘要

The minute pressure measuring method is comprised of (a) preparing a remote measuring apparatus(2) composing a light source(5), an optical detector(6), an electronic circuit(7) for position detection and an output displaying part(8), and transmitting the light irradiated from the light source through an optical fiber bundle(3) to a place to be measured, then receiving again the light transmitted through a glass tube(1a) with a measuring probe(4) to transmit light to the remote measuring apparatus(2) through the optical fiber bundle; (b) performing real-time tracking the change of a liquid surface level based on light transmitted to the remote measuring apparatus(2), digitalizing it to display the liquid surface level and a minute pressure on the output displaying part(8).
