Internal Structure of Diffuse Silicon Pressure sensor
From: Issued date 2023.02.13 Back
Diffuse silicon pressure sensor is the core component for manufacturing pressure sensors and transmitters. Taking Nanjing Wotian diffusion silicon pressure core as an example, I will talk about the internal structure of the diffuse silicon pressure sensor.
Diffuse silicon pressure sensor is composed of compensation plate, steel ball, base, O-ring, chip, ceramic pad, diaphragm, pressure ring, silicon oil, etc.
In the structure in figure, each part has a corresponding role and characteristics：
Compensation board: signal amplification
Steel ball: sealing oil
Base: the carrier of the pressure sensor
Chip: Feeling Stress
Ceramic Mat: Filled
Diaphragm: contact liquid or gas for measurement
Pressure ring: welding the diaphragm to the base
Silicon oil: conductive pressure
The above is about the structure and function of Nanjing Wotian pressure sensor. If you have some words, welcome to talk with the editor.
