    Description

    Vintage very accurate field micrometric barometer M-111 for barometric leveling
    The main part (pressure sensor) of the devices is one or two aneroid blocks, each of which is a metal corrugated membrane box filled at a certain pressure with an inert gas. When the atmospheric pressure changes, the corrugated membrane surface is deformed. These deformations through a system of levers and springs are transferred to the mirror, causing it to turn. The angular movement of the mirror is fixed by means of an optical reading device.
