The Bourdon tube, a hollow, tubular structure meticulously crafted from elastic material, comes in a variety of shapes—including, but not limited to, C-shaped, spiral, and coil designs. Its origins can be traced back to the groundbreaking invention of French engineer E. Bourdon, which is why it’s also known as the Bourdon tube. Today, it continues to play a vital role across numerous fields. The free end of this type of tubing is designed to be flexible and movable, while the open end remains fixed.

The Bourdon tube, a hollow, tubular structure meticulously crafted from elastic material, comes in a variety of shapes—including, but not limited to, C-shaped, spiral, and coil designs. Its origins can be traced back to the groundbreaking invention of French engineer E. Bourdon, hence the name "Bourdon tube," which continues to play a vital role across numerous fields today. This type of tubing features a freely movable free end while its open end remains fixed. When fluid flows through the tube and pressure is applied, the Bourdon tube deforms accordingly, causing its free end to undergo significant linear or angular displacement. The measurement range is remarkably wide, spanning from tens of kilopascals all the way up to over one gigapascal.

Additionally, spring tubes come in a variety of cross-sectional shapes—elliptical, flattened, and circular—each offering unique advantages. Flattened tubes are particularly well-suited for low-pressure environments, while circular tubes excel in high-pressure applications. Notably, the helical spring tube features an ingenious design that perfectly meets the precision requirements of instruments demanding high displacement accuracy.
