Tip: Internal Structure of Diffused Silicon Pressure sensor

Diffusion silicon pressure sensor is the core component for manufacturing pressure sensors and pressure transmitters. Taking Nanjing Wotian diffusion silicon pressure sensor as an example, let's talk about the internal structure of the diffusion silicon pressure sensor.

Diffused silicon pressure sensor is composed of compensation plate, steel ball, base, O-ring, chip, ceramic pad, diaphragm, pressure ring, silicone oil, etc.

The structure shown in the 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 opinions, welcome to talk with the editor.
