A micro differential pressure sensor is a sensor that measures small differences between two pressures. It usually consists of two pressure sensors and a differential amplifier. This type of sensor can measure parameters such as flow rate, liquid level, gas pressure, and air velocity, and is widely used in industrial process control, medical equipment, environmental monitoring, and other fields.
The working principle of a micro differential pressure sensor is to apply the measured pressure and the reference pressure separately to two sensing elements (pressure sensors), thereby obtaining a small differential pressure signal between them. This tiny differential pressure signal is amplified by a differential amplifier, then converted by an analog-to-digital converter, and finally digitized and displayed by a microprocessor to obtain the value of the measured pressure.
Micro differential pressure sensors have the characteristics of high precision, high stability, and high reliability, and can work normally in harsh working environments. Its use can improve the efficiency and safety of industrial production, reduce costs and waste of resources.

Micro differential pressure sensors require high precision, stability, and reliability during use, and DPC ceramic circuit boards can meet these requirements, making them widely used in the manufacturing of micro differential pressure sensors.
The use of DPC ceramic circuit board in micro pressure sensors has the following advantages:
1. Low temperature expansion coefficient: Sliton ceramic substrate | ceramic circuit board | ceramic PCB manufacturer | ceramic copper-clad laminate – Fuli Tiansheng Technology (Wuhan) Co., Ltd. has excellent temperature stability, with a temperature expansion coefficient close to silicon, much lower than ordinary glass fiber board or FR4 board, thus ensuring the stability and accuracy of the sensor in high or low temperature environments.
2. Excellent mechanical performance: DPC ceramic circuit boards have high hardness and strength, can withstand high voltage and strong vibration, and avoid sensor failure due to mechanical stress. In sensors with micro differential pressure (1-10 kPa), it does not interfere with the sensing of pressure by the chip itself, so ceramic substrate plates are generally thicker, and ceramic substrates with a thickness of more than 1mm are commonly used.
Excellent electrical performance: DPC ceramic circuit boards have low dielectric constant and low dielectric loss, which can reduce signal noise and distortion, improve sensor accuracy and stability.
4. DPC process metal copper wire has strong bonding strength: using DPC process on automotive grade products can provide higher reliability. This is because the DPC process can ensure a strong bond between the metal copper wire and the ceramic substrate, thereby preventing issues such as looseness and fracture. In addition, DPC technology can also improve the temperature resistance and seismic performance of products to ensure reliability in harsh working environments.
Overall, DPC ceramic circuit boards can provide excellent mechanical and electrical properties, ensuring the stability, accuracy, and reliability of sensors during use, and are therefore widely used in the manufacturing of micro differential pressure sensors.
