BM4 type aneroid barometer is a device for sensing the deformation of a barometric pressure measuring instruments. It easy to carry, accurate measurement, pressure measurement range, use the easy maintenance, no mercury, etc., widely used in meteorology, military, aviation, marine, agriculture, surveying, geological, industrial and mining enterprises and scientific research in areas such as measurement atmospheric pressure of conventional instruments.
Second, the principle:
Aneroid barometer by atmospheric pressure changes with the axial movement of the air induction box as the original group, which led through the rod and the transmission pointer, indicating the prevailing atmospheric pressure.
