HT12 Silicon Piezoresistive Pressure SensorIntroduction of silicon pressure sensor:HT12 silicon piezoresistive pressure sensor is a highly stable
diffusion silicon element packaged in advanced TO8 packaging
technology. The non-oil-filled core avoids the profile error and
significantly improves the stability of the small range. Therefore,
it has a good effect on the measurement of 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.
- 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. During assembly, attention should be paid to the coordination
between the core size and the transmitter housing to achieve the
required tightness.
2. During the housing assembly process, ensure that it is
vertically aligned and apply even pressure to avoid jamming or
damaging the compensation plate.
3. If the medium under test is incompatible with the chip and
housing material (316L), special instructions should be provided
when placing the order.
4. Avoid pressing the inside of the sensor with hands or sharp
objects to avoid deformation or puncture of the diaphragm and
damage to the core.
5. Keep the pressure port of the gauge core open to the atmosphere
to prevent water, water vapor or corrosive media from entering the
negative pressure chamber of the gauge core.
6. If any pin changes, refer to the label on the actual core wire.
