HT12 Silicon Piezoresistive Pressure Sensor Introduction of silicon pressure sensor:
The HT12 silicon piezoresistive pressure sensor is a highly stable diffusion silicon element packaged using advanced TO8 packaging technology. The non-oil-filled core eliminates profile errors and significantly enhances the stability of the small range, making it particularly effective for measuring dry non-corrosive gas pressure.
Product Features of silicon pressure sensor: - The measurement range is wide from 0 to 10KPa to 2Mpa.
- High reliability, good stability.
- TO8 encapsulation technology.
- Aerospace applications.
Applications of silicon pressure sensor: - Dry, non-corrosive gas pressure was measured.
- The pneumatic control systemMedical applications of biomedical engineering.
- Hvac (HVAC) controls.
- Aerospace aviation related to the purpose of experiment.
Electrical performance of silicon pressure sensor: - Power Supply: ≤2mA DC (Typical 1.5mA DC)
- Input Impedance:3KΩ~6KΩ
- Output Impedance:2.5KΩ~6KΩ
- Electrical Connection:Gold-plated Kovar pins or 100mm high-temperature wires

1. Pay attention to the matching of the core size and the transmitter housing during assembly to achieve the required air tightness.
2. During assembly, ensure the vertical alignment and apply even pressure to prevent jamming or damaging the compensation plate.
3. Keep the gauge pressure core air duct connected to the atmosphere and prevent water, water vapor, or corrosive media from entering the positive and negative pressure chambers of the core.
4.If there are any changes in the pin lead, refer to the label attached to the core for accurate identification.
