Atmospheric pressure gauge 

1 Purpose Features
     DYM3 type aneroid barometer is based on a deformable element for sensing atmospheric pressure measuring instruments. It is easy to carry, accurate measurement, wide load range, easy maintenance, no mercury pollution, etc., are widely used in meteorology, military, aviation, marine, agriculture, surveying, geology, industrial and mining enterprises and scientific research fields, as measured atmospheric pressure of a conventional instrument.

2 Works
     Aneroid barometer is made of an elastic metal thin film sensing element as an empty box, it will empty boxes atmospheric pressure into an elastic displacement, driven pointer through the lever and the transmission mechanism. When clockwise deflected pointer indicates the amount of change in outlet pressure is increased, and vice versa, when the pointer counterclockwise direction, indicating the amount of change in the air pressure decrease. When an empty box of elastic stress and atmospheric pressure equilibrium, the pointer will stop turning, then the pressure indicated by the pointer value is the prevailing atmospheric pressure.
