The selection of pressure transmitters is mainly based on the measured medium, temperature environment, accuracy level, installation and maintenance costs, etc. After determining the manufacturer and model of the transmitter used, the range of the transmitter is determined according to the usage requirements. When selecting the range, the principles of adjustable range up and down, qualified accuracy, and suitable price should be comprehensively considered.

With the development of technology, BD pressure transmitters have gradually taken the stage in many industries. After decades of development, frequency conversion control has become a major tool for saving electricity, improving consumption processes, increasing production volume, and improving operating environments. The transmitter is of great significance in the entire mechanical manufacturing industry in China. It is commonly used in the transmitter market and industry processes. The transmitter market in China is relatively mature, and apart from the market for new projects, there are some technical exchanges every year.

The ability of a pressure transmitter to maintain its function unchanged after a period of use is called stability. The factors that affect the long-term stability of the transmitter are not only the structure of the transmitter itself, but also the operating environment of the transmitter. Therefore, in order for the transmitter to have good stability, it must have strong environmental adaptability.

The stability of pressure transmitters has quantitative indicators. After exceeding the service life, they should be recalibrated before use to determine whether the function of the transmitter has changed. In some situations where the transmitter is required to be used for a long time but cannot be replaced or calibrated casually, the stability requirements for the selected transmitter are more stringent, and it must be able to withstand long-term tests.
