History Of Pressure Measuring Instruments
- Aug 21, 2018 -

In 1643, Italian torricelli first measured the standard atmospheric pressure of 760 mm hg, laying the foundation of liquid-column pressure gauge. In 1847, French bourdon made pressure gauges with bourdon tube. Due to its simple and practical structure, it has been widely used in industry and has always been a common pressure measuring instrument.

In the first half of the 20th century, the remote pressure gauge and the electric contact pressure gauge appeared, which solved the problems of long-distance transmission of pressure measurement value and alarm and control of pressure. After the 1960s, in order to adapt to the requirements of industrial control, aviation industry and medical testing, pressure measuring instruments were increasingly developed in the direction of light volume, high temperature resistance, impact resistance, vibration resistance and digital display
