Pressure Transmitter Research Status and Development Trend
As an important measuring instrument in industrial field,pressure transmitter has been widely used in thermal power,nuclear power,chemical industry,steel,aerospace,and other fields.With the development of detection technology and automation technology,the stability,accuracy,and intelligence level of pressure transmitter has put forward more stringent requirements.The main structure and common classification of pressure transmitters are introduced.The research and application status of pressure transmitters from various aspects are analysed such as communication methods,special environmental measurement requirements and intelligence.The communication mode of pressure transmitter has been developed from traditional analog communication to convenient wireless communication.For high temperature extreme environment pressure measurement,new materials such as silicon carbide,graphene and other are used as sensor sensitive components.In order to adapt to the demand for intelligence,some researchers designed and developed pressure transmitter with self-diagnostic function,so as to protect the safety of the system.In order to overcome the temperature drift problem of pressure sensor,various neural network and deep learning temperature compensation algorithms have been proposed.Wireless,intelligent,high-precision and so on will become the main development direction of pressure transmitter in the future.
