The diffusion silicon pressure sensor is a core component used in the manufacturing of pressure sensors and pressure transmitters. In this article, we will explore the internal structure of the XIDIBEI diffusion silicon pressure sensor.
The XIDIBEI diffusion silicon pressure sensor is composed of several parts, including a compensation plate, steel ball, base, O-ring, chip, ceramic pad, diaphragm, pressure ring, and silicone oil.
Let us take a closer look at each of these components and their corresponding functions in the internal structure of the diffusion silicon pressure sensor.
Compensation Plate: Signal Amplification
The compensation plate is responsible for signal amplification. It amplifies the weak electrical signals produced by the chip, enabling the sensor to detect and measure changes in pressure accurately.
Steel Ball: Oil Sealing
The steel ball is used to seal the silicone oil inside the sensor. It prevents the oil from leaking out and ensures that the sensor operates smoothly and accurately.
Base: Carrier of Pressure Sensor
The base serves as the carrier of the pressure sensor. It supports the other components and provides stability to the sensor.
The O-ring is responsible for sealing the sensor and preventing any external factors such as dust, moisture, or other contaminants from entering the sensor.
Chip: Pressure Sensing
The chip is the most critical component of the diffusion silicon pressure sensor. It is responsible for sensing the pressure changes and converting them into electrical signals. The chip is made of high-quality silicon material that can withstand high pressures and temperatures.
Ceramic Pad: Filling
The ceramic pad is used to fill the gap between the chip and the diaphragm. It ensures that the pressure is uniformly distributed across the diaphragm, enabling the sensor to produce accurate measurements.
Diaphragm: Contacting Measured Media
The diaphragm is a thin, flexible component that comes into contact with the media being measured, such as liquids or gases. It deforms under pressure, causing the chip to produce electrical signals that correspond to the pressure changes.
Pressure Ring: Welding the Diaphragm to the Base
The pressure ring is used to weld the diaphragm to the base. It ensures that the diaphragm is securely attached to the base and that pressure changes are accurately transmitted to the chip.
Silicone Oil: Conducting Pressure
The silicone oil is used to conduct pressure from the diaphragm to the chip. It acts as a medium for transmitting the pressure changes, enabling the chip to produce accurate electrical signals.
In conclusion, the XIDIBEI diffusion silicon pressure sensor is a highly precise and reliable component used in pressure measurement applications. Its internal structure is composed of several components that work together to ensure accurate and stable pressure sensing. Understanding the internal structure of the sensor can help users troubleshoot any issues that may arise and make informed decisions when selecting pressure sensors for their applications.
