19mm Diffused Silicon Pressure Sensor Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT19 piezoresistive silicon pressure sensor, the main component is a high stability diffuse silicon sensing element. It is a semiconductor-based device that converts mechanical pressure into an electrical signal by leveraging the piezoresistive effect in silicon. It is widely used in industrial, automotive, medical, and consumer applications due to its high sensitivity, miniaturization potential, and cost-effectiveness.
Product Features of silicon pressure sensor:
- High Sensitivity: Detects minute pressure changes (e.g., <1 mbar).
- Linear Output: Well-characterized response to pressure variations.
- Compact Size: MEMS technology enables integration into small systems.
Applications of silicon pressure sensor:
- Measurement pressure of gas and liquid
- Petroleum exploitation
- Water supply,warm supply of town
- Process control system
- Aviation and navigation inspection
- Hydraulic pressure

Dimension
Note:
1. Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the required air tightness
2. During the assembly of the housing, ensure it is aligned vertically and apply even pressure to avoid jamming or damaging the compensation plate.
3. If the measured medium is not compatible with the core diaphragm and the housing material (316L), special instructions should be provided when placing the order.
4. Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage to the core due to diaphragm deformation or piercing.
5. Keep the pressure port of the gauge pressure core open to the atmosphere and prevent the entry of water, water vapor, or corrosive media into the core negative pressure chamber.
6. If there are any changes to the pin leads, follow the label on the actual core for reference.
