The oil industry is a precision machining industry, requires a high degree of accuracy of measurement of the pressure sensor. In the control system, the precision of the pressure sensor measurement value, the higher the control more accurate. Oil industry the precision of the pressure sensor value reached 0.075%, basic can meet the use requirement.

With the development of oil and gas industry, China's oil and gas pipeline construction has made great progress. At present, pipeline transportation has become the main mode of transportation of oil and gas. China's current oil and gas pipelines in 60% of the pipeline has been running for 20 years or so, in the eastern part of some crude oil tube has been running for more than 30 years. Because of the oil pipeline corrosion and theft, many serious aging pipeline, pipeline leakage happens often, cause energy waste and environment pollution.

Traditional pipeline leak detection methods are usually based on the pressure sensor to collect the pressure signal of pipeline, and through the pressure changes to determine the pipe blockage or leakage point. The application of the pipeline detection method to transmit and display the pressure signal, however, when the pressure signal transmission distance is longer, the use of traditional pressure detection device to transmit signals for background noise is big, pressure signal attenuation problem cannot meet the requirements of the pressure signal acquisition and processing. Therefore, in the process of production, stable and reliable pressure transducer is a powerful tool for ensuring continuous production process.

Because if there is a measurement error, may lead to shut down, the resulting economic losses will be enormous. Therefore, this is the oil industry the most basic demand for pressure sensor.
 

The oil industry is a precision machining industry, requires a high degree of accuracy of measurement of the pressure sensor. In the control system, the precision of the pressure sensor measurement value, the higher the control more accurate. Oil industry the precision of the pressure sensor value reached 0.075%, basic can meet the use requirement.

The following simple said the oil pipeline and the principle of the pressure sensor in: oil pipeline pressure sensor working principle is: medium pressure directly on the pressure sensor on the diaphragm of the diaphragm micro displacement is proportional to the medium pressure, to change the electrical resistance of the sensor and testing electronic circuit of this kind of change, the transformation output pressure with the corresponding standard signal. Petrochemical industry is far more than the above requirements to the requirement of pressure sensor, also including the types and range of the pressure sensor bus ratio, etc. Compared with increased pressure sensor, increase the measurement range is more flexible, it has brought great convenience for the design and application process.

The oil industry has a high requirement on the performance of the pressure sensor, today, most of the products is still dependent on imports. Obviously, this is a challenge to domestic pressure sensor industry.
