Miscellaneous

KJ3F10A98SN is a type of pressure sensor commonly used in the industrial field. It is designed to measure the absolute pressure of a liquid or gas by generating a digital output signal proportional to the input pressure. It is widely used in automation systems, pressure monitoring and control systems, and other industrial applications.

Application Field

The KJ3F10A98SN pressure sensor is suitable for the measurement and control of various pressure ranges, such as liquids or gases in the range of 0 to 10000 Pa. It is widely used in automation systems such as pressure monitoring and control, industrial systems, and other industrial measurement applications. This type of pressure sensor is also suitable for testing gas pipeline pressure, chemical pipeline pressure, air bag pressure, hydrogen tank pressure, and other pressure measurement applications.

Working Principle

The KJ3F10A98SN pressure sensor consists of a pressure sensitive element and an integrated electronic circuit. The pressure sensitive element is composed of a measuring diaphragm and a steel structure. The diaphragm is a connected parts with pressure sensor, when the physical parameters have changes, it will make diaphragm to have deformation, strain gauge or piezoresistive semiconductor are installed on the diaphragm, the diaphragm produce corresponding electrical signal according the changes. After signal processing by integrated circuit, it will output the digital output signal to reflect the pressure change.

When the diaphragm deformed by pressure changes, the strain gauge or piezoresistive semiconductor on diaphragm will fluctuate slightly, the wafer pressure sensor converts the changes of the semiconductor resistance to the variation of voltage, amplified by the amplifiers circuit, then sent to the A/D converter, finally, get the output of digital signal. By comparing the digital signal with the predetermined standard signal and using the control circuit to determine the size of the pressure, thus to realize the measurement.

Conclusion

The KJ3F10A98SN pressure sensor is a type of pressure sensor which has been widely used in industrial applications. It can measure and control the pressure of all kinds of liquid and gas in the range 0 to 10000Pa. It is an ideal choice for pressure monitoring and control systems in the automation systems. Its working principle is based on the principle of converting the change of resistance of the pressure sensitive diaphragm into a digital output signal, and the accuracy and reliability of the pressure measurement are improved by the A/D converter and signal processing circuit.
