Internal Structure of Diffuse Silicon Pressure sensor

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

O-ring: sealed

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.
