In the use of actual on-site working conditions, the stability and reliability of the pressure transmitter have become a strong guarantee for the production process. If there is a measurement error in the process of use, the ensuing economic loss may be immeasurable.
The measurement of the pressure transmitter drifts as the operating environment and static pressure change. In some small pressure or differential pressure measurement cases, this drift is likely to be more serious. Under different working conditions, the most accurate measurement is obtained, so as to maintain the stability of production and ensure the consistency of the process, which is the embodiment of the stability of the pressure transmitter.
In the use of field working conditions, the demand for pressure transmitters is mainly concentrated in three aspects: reliability, stability and high precision. The stability and high accuracy of the pressure transmitter are mainly ensured by the stability and measurement accuracy of the pressure sensor. The measurement accuracy of the pressure transmitter corresponds to the measurement accuracy and response speed of the pressure sensor, and the stability of the pressure transmitter corresponds to the temperature and static characteristics of the pressure sensor and the long-term stability.
The stability of a pressure transmitter is a key time-dependent indicator of transmitter performance. One of the factors that affect the stability of a pressure transmitter is the measuring range. Typically, a pressure transmitter that is 1.5 times larger than the maximum value of the medium is required. Another factor that affects the long-term stability of a pressure transmitter is the environment in which it is used. Before selecting a pressure transmitter, it is necessary to investigate the environment in which it will be used, and select the appropriate transmitter according to the detailed usage environment, or take appropriate measures to reduce the impact of the environment.
