Pressure sensor to detect pipeline leaks brings convenience to the oil industry

[ Focus on Chemical Machinery Equipment Network ] With the development of the oil and gas industry, China's oil and gas pipeline construction has made great progress.
At present, pipeline transportation has become the main method of oil and gas transportation.
The traditional pipeline leak detection method is usually based on the pressure sensor to collect the pressure signal in the pipeline, and through the pressure change to determine whether the pipeline is blocked or there is a leakage point.
This pipeline detection method needs to transmit and display the pressure signal during application.
However, when the transmission distance of the pressure signal is long, the traditional pressure detection device is used to transmit the pressure signal.
Because the background noise is large, the pressure signal attenuation and other issues cannot meet the requirements.
Requirements for pressure signal acquisition and processing.

Therefore, in the oil production process, a stable and reliable pressure sensor is a powerful tool to ensure a continuous production process.
Because if there is a measurement error, it may cause work stoppage, and the resulting economic loss will be huge.
Therefore, this is the most basic demand for pressure sensors in the petroleum industry.

The petroleum industry is a precision processing industry, which has high requirements for the measurement accuracy of pressure sensors.
In the control system, the higher the accuracy of the pressure sensor measurement, the more precise the control.
The accuracy value of the pressure sensor in the petroleum industry reaches 0.
075% before it can basically meet the requirements of use.  

　　The working principle of the pressure sensor:
 

　　The pressure of the medium directly acts on the diaphragm of the pressure sensor, causing the diaphragm to produce a micro displacement proportional to the pressure of the medium, changing the resistance of the sensor and detecting this change in the electronic circuit, and converting and outputting a standard signal corresponding to this pressure.
The petrochemical industry's requirements for pressure sensors far exceed the above requirements, including "the type and range ratio of the pressure sensor bus".
Compared with adding a pressure sensor, increasing the measurement range is more flexible, which brings great convenience to the design and application process.

 

　　The petroleum industry has high requirements for the performance of pressure sensors.
Today, most products still rely on imports.
Obviously, this is a challenge to the domestic pressure sensor industry.
