HT12 Silicon Piezoresistive Pressure SensorIntroduction of silicon pressure sensor:The HT12 silicon piezoresistive pressure sensor is a highly stable
diffusion silicon element encapsulated using advanced TO8 packaging
technology. The absence of an oil-filled core eliminates profile
errors and significantly improves the stability of the small range,
rendering it particularly suitable 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.
- 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

- Ensure a precise fit between the sensor core and the housing during
assembly to achieve the required air-tight seal.
- Carefully align the components vertically and apply uniform
pressure when assembling to avoid jamming or damaging the
compensation plate.
- Maintain an open connection between the pressure sensor core's air
duct and the atmosphere, preventing water, vapor, or corrosive
substances from entering the positive and negative pressure
chambers.
- If any changes are made to the pin leads, refer to the label
attached to the sensor core to identify them accurately.
