Advanced Micro Pressure Sensors | Yatan Instrument (Shanghai) Solutions
Micro pressure sensors are critical components in modern industrial automation and intelligent control systems. Shanghai Yatan Instrument & Meter Co., Ltd. specializes in high-precision pressure sensing solutions, providing reliable micro pressure sensors for industrial, medical, and environmental applications.
1. Overview of Micro Pressure Sensors
A micro pressure sensor is a highly sensitive device designed to measure extremely small pressure variations (in Pascal level). It converts pressure changes into electrical signals and is widely based on MEMS (Micro-Electro-Mechanical Systems) technology, offering high accuracy, compact size, and low power consumption.
2. Structure of Micro Pressure Sensors
- Sensing Chip: MEMS silicon chip or thin-film structure
- Diaphragm: Deforms under pressure
- Signal Conditioning Circuit: Amplifies and converts signals
- Housing: Stainless steel or ceramic enclosure
Micro pressure sensors typically operate based on piezoresistive or capacitive principles, where pressure causes deformation of the sensing diaphragm and results in electrical signal changes. :contentReference[oaicite:2]{index=2}
