Small changes in differential pressure often hide large fluctuations in system operation. Whether it is gas-liquid transportation in chemical reaction process or pipeline differential pressure control in oil refining, accurate monitoring of micro differential pressure is the key to ensure stable production and safe operation. The AS800 single crystal silicon micro differential pressure sensor launched by ATECH is carefully built based on this application demand and designed for high-demand working conditions. It is widely used in petroleum, chemical, power and other industries with excellent performance.
The chemical industry has extremely high requirements for differential pressure control, especially in equipment such as filtration systems. Slight pressure fluctuations may mean blockage, leakage or even process out of control. This scenario places extremely high demands on the accuracy, response speed and long-term stability of the sensor. The single crystal silicon micro differential pressure sensor adopts a single crystal silicon sensor core imported from Germany. The suspended structure not only has good seismic performance, but also effectively improves the pressure resistance and measurement stability. The product can still maintain a measurement accuracy of 0.1% within the micro differential pressure range of -50~50Pa, which is very suitable for chemical processes that are extremely sensitive to small pressure differential changes.
In the field of petroleum, whether it is a refinery, pipeline transportation system or separation device, the measurement environment is often accompanied by high temperature, high pressure and strong corrosion. The contact medium material of the single crystal silicon micro differential pressure sensor is 316 stainless steel, which has excellent corrosion resistance and can operate stably for a long time in complex media environments such as acid, sulfur and oil. The product has excellent overpressure capacity and can withstand a back pressure shock of up to 1MPa under the 1kPa range state. It can effectively prevent the damage of the sensor body by abnormal pressure on site and improve the overall safety and reliability of the system.
In terms of ease of use, the product is equipped with a 5-digit LCD digital display with backlight, supports switching between multiple pressures and engineering units, and is intuitive and convenient to operate; it supports three-button local quick parameter setting, and can also be connected to the DCS or PLC system through the HART protocol to achieve remote debugging and intelligent configuration. In addition, the full temperature range compensation and static pressure compensation functions can ensure the accuracy and consistency of the output signal even in environments with severe temperature differences such as outdoor oil fields and coastal platforms.
The single-crystal silicon micro-differential pressure sensor can promptly feedback the alarm when the sensor is abnormal, which is convenient for on-site operation and maintenance personnel to quickly respond and maintain, and minimize the risk of shutdown caused by system failure. The product adopts cable introduction, the electrical connection is safe and reliable, with IP66 level protection, and is suitable for various harsh outdoor working conditions.
