What is a pressure transmitter? To put it simply, a pressure transmitter is a kind of “pressure value” that converts the “pressure value” into a pneumatic signal or an electric signal to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement, indication and process adjustment. 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. Early pressure transmitters used a large-displacement operating principle, such as mercury float differential pressure gauges and diaphragm differential pressure transmitters, which were mass-produced, which were inaccurate and cumbersome. In the 50s of the 20th century, there was a force balance differential pressure transmitter with slightly higher precision, but the feedback force was small, the structure was complex, and the reliability, stability and vibration resistance were poor. 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. In the 90s, with the rapid development of science and technology, these pressure transmitters have high measurement accuracy and gradually develop to intelligence, and digital signal transmission is more conducive to data acquisition. In the 21st century, the digital intelligent transmitter has gradually entered our field of vision, and the pressure transmitter adopts advanced detection technology to eliminate the influence of moisture, dust and other harsh on-site environments on the transmitter measurement, and the accuracy is higher. Pressure transmitters can be divided into different types such as capacitive pressure transmitters, diffusion silicon piezoresistive pressure transmitters, and differential inductive pressure transmitters.
