Bourdon tube pressure gauge is a commonly used pressure measuring instrument, its working principle is based on the mechanical characteristics of the spring to achieve measurement. The instrument is simple in structure and easy to operate, and is suitable for pressure measurement in many occasions. The working principle of the

spring tube pressure gauge is based on Hooke's law and the principle of elastic deformation. When the pressure acts on the pressure element, the spring tube elastic deformation, the resulting elastic force becomes the force to measure the pressure. According to Hooke's law, the elastic deformation of the spring tube is proportional to the pressure, so the pressure can be directly measured by the deformation of the spring tube. The advantages of

spring tube pressure gauge are simple structure, low cost, wide range, high precision, and long service life. At the same time, the instrument can also meet different working conditions by adjusting the number and material of the spring tube. The disadvantage of

spring tube pressure gauge is that it has a small range, is easily affected by temperature, and its service life is affected by spring material. In addition, the spring tube pressure gauge also requires regular calibration and maintenance to ensure measurement accuracy and service life.

in the use of bourdon tube pressure gauge, need to pay attention to a few points: to choose the appropriate range and accuracy, to meet the needs of the work; to keep the pressure gauge clean and dry; finally, the use of the operation in accordance with the instructions to avoid operating errors and damage to the instrument.

spring tube pressure gauge is a simple and practical pressure measuring instrument, its working principle is based on the principle of elastic deformation, can be applied to a variety of occasions of pressure measurement. In the selection, use and maintenance, it is necessary to operate in accordance with the requirements to ensure its measurement accuracy and service life.
