What is a pressure transmitter Definition of a pressure transmitter: To put it simply, a pressure transmitter is a device that converts “pressure” into a pneumatic signal or an electric signal for control and remote transmission. The pressure transmitter is the most commonly used transmitter in the field of industrial automation, which involves many industries and fields such as water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, petrochemical, electric power, shipbuilding, machine tools, pipelines, etc. History of pressure transmitters: First, the early pressure transmitters used the working principle of large displacement, such as the mercury float differential pressure gauge and the membrane box differential pressure transmitter that were mass-produced, which had low accuracy and bulky. Second, in the 50s of the 20th century, there was a force balance differential pressure transmitter with slightly higher precision, but the feedback force is small, the structure is complex, and the reliability, stability and vibration resistance are poor. 3. In the mid-70s, with the emergence of new processes, new materials and new technologies, especially the rapid development of electronic technology, displacement transmitters with small size and simple structure appeared. Fourth, the rapid development of science and technology in the 90s, these pressure transmitters have high measurement accuracy and gradually develop to intelligence, and digital signal transmission is more conducive to data acquisition. Types of pressure transmitters: Pressure transmitters can be divided into different types such as capacitive pressure transmitters, diffusion silicon piezoresistive pressure transmitters, differential inductive pressure transmitters, etc. Development Trends of Pressure Transmitters: 1. Intelligence: Due to the emergence of integration, some microprocessors can be added to integrated circuits, so that the transmitter can have some functions such as automatic compensation, communication, and logical judgment. 2. Integration: Nowadays, the pressure transmitter has been more and more integrated with the transmitter for its measurement, and the measurement and control system has been formed, and the integrated system can be controlled and automated in the factory to improve the operation speed and work efficiency in the process of use. 3. Universalization: Another development trend of pressure transmitters is expanding from the machinery industry to other fields, such as automotive components, medical instruments and energy and environmental control systems. 4. Standardization: In the future design and manufacture of transmitters, a complete set of industry standards needs to be formed to standardize the transmitter industry. Fifth, miniaturization: the market for small pressure transmitters is more and more demanding, for this small transmitter can work in an extremely harsh working environment, and only requires very little maintenance and maintenance time, the impact on the surrounding environment is also very small, the future can also be placed in the human body in various important organs to collect data, and will not affect the normal life of people.
