Development Trend of Pressure Transmitter

Pressure transmitters are important components used in many industrial equipment to control industrial processes and pressure changes. The pressure transmitter is used to measure the level, density and pressure of liquid, gas or steam, and then convert the pressure signal into a 4~20mADC signal output. Pressure transmitters are divided into capacitive pressure transmitters, diffused silicon pressure transmitters, ceramic pressure transmitters, strain gauge pressure transmitters, etc.

Pressure transmitters are field instruments that are in direct contact with the measured medium. They often work in environments such as high temperature, low temperature, corrosion, vibration and impact. It is widely used in pressure measurement and on-site control in petroleum, chemical industry, electric power, steel, light industry and other industries.

Today, the research field of pressure transmitters in various countries around the world is very extensive and has penetrated into almost every industry. However, in summary, there are mainly the following trends:

1. Intelligentization: Due to the emergence of integration, some microprocessors can be added to the integrated circuit, so that the transmitter has functions such as automatic compensation, communication, self-diagnosis, and logical judgment.

2. Integration: Pressure transmitters have been increasingly integrated with other measurement transmitters to form measurement and control systems. Integrated systems increase operational speed and efficiency in process control and factory automation.

3. Miniaturization: The market demand for small pressure transmitters is increasing. This small transmitter can work in extremely harsh environments and requires very little care and maintenance, and has little impact on the surrounding environment. It is very small and can be placed in various important organs of the human body to collect data without affecting people’s normal life.

4. Standardization: The design and manufacturing of transmitters have formed certain industry standards.

5. Broadening: Another development trend of pressure transmitters is expanding from the mechanical industry to other fields, such as automotive components, medical instruments and energy and environmental control systems.
