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.

| Ordering tips |
1. Pay close attention to the alignment and fit between the sensor core and the housing during assembly to ensure the required air tightness.
2. Maintain proper vertical alignment and apply even pressure during assembly to prevent jamming or damage to the compensation plate.
3. Keep the pressure sensor core's air duct connected to the atmosphere and prevent water, moisture, or corrosive media from entering the positive and negative pressure chambers.
4. If there are any changes to the pin leads, refer to the label attached to the core for accurate identification.
