Mechanical Pressure Gauge

 

During insustrial controlling and measuring process. The elastic sensitive element of the mechanical pressure gauge is used widely in all kinds of industrial fields due to its high mechanical strength, low price and convenient production methods. The mechanical pressure gauge is often made of Bourdon tube, diaphragm, capsule or bellow tube. These elements should be elastic deformed by the medium pressure. The signals would be enlarged by the movements, and the pointer should then be able to point to the number on the dial, to indicate the pressure. The effective measuring range on the dial is usually within 270 degree of a circle.
