Summary: the pressure sensor is the most commonly used one kind of sensor, its widely used in various industrial control environment, involved in water conservancy and hydropower, railway transportation, intelligent buildings, production control, aerospace, military industry, petrochemical, oil, electric power, ships, machine tools, pipe, and many other industries, we will introduce the application of some commonly used pressure sensors.
An industrial automation system is usually divided into three parts: detection, control and execution. As the control object of automation system, industrial equipment must be compatible with two other parts and provide the pressure sensor interface to make it a complete organic whole. The control objects should be protected from either automation or large automation devices to maximize their use.
The application of intelligent pressure sensor in petrochemical industry
The intelligent pressure sensor is one of the most used measurement devices in the automatic control of petrochemical industry. In large chemical project, including nearly all of the application of pressure sensor, differential pressure, absolute pressure, gauge pressure, high temperature, low temperature, high pressure, differential pressure, as well as a variety of materials and special processing of far eastone flange type pressure sensor.
The demand for pressure sensors in the petrochemical industry mainly focuses on reliability, stability and high accuracy. Among them, reliability and many additional requirements, such as the range ratio and bus type, depend on the structural design of the transmitter, the mechanical process level and the structural material. The stability and high accuracy of pressure transducer are mainly guaranteed by the stability of pressure sensor and measurement precision. And measurement accuracy of pressure transmitter is corresponding to the pressure sensor of measuring precision and response speed, and the stability of the pressure transmitter is corresponding to the pressure sensor temperature characteristic and static characteristic and long-term stability. The demand of the petrochemical industry for pressure sensors is reflected in the measurement precision, fast response, temperature characteristics and static pressure characteristics and long-term stability.
MaiDeSheng micro pressure sensor is made using semiconductor materials and MEMS technology a new type of pressure sensor, with high accuracy, high sensitivity, good dynamic performance, small volume, corrosion resistance, low cost advantages. The material of pure monocrystalline silicon is small, and the long - term stability of the micro - pressure sensor made by this material is good. At the same time, the micro pressure sensor is easy to integrate with the micro-temperature sensor to increase the temperature compensation accuracy, and greatly improve the temperature and measurement precision of the sensor.
If two micro-pressure sensors are integrated, static pressure compensation can be realized to improve the static pressure characteristics of the pressure sensor. The McDwin micro pressure sensor has the advantages of many traditional pressure sensors, which can meet the demands of the petrochemical industry for pressure sensors.
