The introduction of Bellows pressure gauge

Bellows pressure gauge is a commonly used pressure measuring instrument, its working principle is to use the deformation of bellows to measure the pressure of the measured medium. A corrugated pipe is a thin-walled metal pipe formed by a plurality of ripples, which is characterized by high elasticity and deformation ability.

When the pressure of the measured medium acts on the inside of the bellows, the bellows will bend and deform, and this deformation will cause the displacement of the two ends of the bellows to change. The displacement change at both ends of the bellows can be measured by sensors connected to both ends of the bellows to obtain the pressure value of the measured medium.

 The accuracy and sensitivity of the bellows pressure gauge are relatively high, and small pressure changes can be measured at the same time, the structure of the bellows pressure gauge is relatively simple, the user makes it suitable for various industries

The accuracy and sensitivity of the bellows pressure gauge are relatively high, and small pressure changes can be measured at the same time, the structure of the bellows pressure gauge is simple, easy to use, and suitable for pressure measurement in various industrial occasions

Note on the use of bellows pressure gauge:

1. Before use, check whether the dial and pointer of the bellows pressure gauge are normal, and whether there is damage or loosening.

2. In use, attention should be paid to the temperature and pressure range of the measured medium, not exceeding the rated range of the bellows pressure gauge

3. In the process of use, the bellows pressure gauge should be avoided by impact or vibration, so as not to affect the measurement accuracy

4. Clean the bellows pressure gauge in time after use, and store it in a dry and ventilated place to avoid moisture or damage. Bellows pressure gauge is a kind of pressure measuring instrument with high precision and convenient use, which is widely used in various industrial occasions. Care and maintenance should be taken during use to ensure its normal work and accurate measurement. Principle and structure of bellows pressure gauge

Bellows pressure gauge A pressure gauge with bellows as measuring elements. When the measured medium enters the bellows, the bellows deform, and the movement is driven by the connecting rod to rotate and the pointer is rotated to achieve the purpose of indicating pressure. The bellows pressure gauge is suitable for a range of 0~1.6kPa to 0~60kPa. Bellows pressure gauge with high overpressure capacity, can achieve 10 times full scale overpressure. The structure of the bellows pressure gauge is shown in the figure.
