Comparison of Performance Among Different Sensitive Materials for Pressure Sensors
The strain-sensitive materials commonly used in pressure sensors include single-crystal silicon, polycrystalline silicon, or multi-component metallic materials such as NiCr alloys. The composition of NiCr alloy-based sensitive materials can be optimized according to the specific application environment or requirements of the sensor. For instance, if a very low temperature coefficient of resistance is required, appropriate elements can be added to reduce temperature drift at high or low temperatures and ensure humidity stability.

After lasting three days, the world’s largest petrochemical exhibition—the China International Petroleum & Petrochemical Technology & Equipment Exhibition—came to a successful close on the afternoon of March 31. The exhibition attracted hundreds of well-known enterprises from both home and abroad, and was covered by dozens of domestic and international media outlets, including CCTV and the People’s Daily. With the advancement of electronic, information, and network technologies, petrochemical equipment is becoming increasingly intelligent, and these devices now incorporate a wide variety of sensor products.
