HT-IQ Silicon Piezoresistive Pressure Sensor
Introduction of piezoresistive silicon pressure sensor :
HT-IQ is a flush diaphragm pressure sensor with a highly stable diffused silicon chip. The pressure is transmitted to the sensitive chip through a stainless steel diaphragmand sealed silicon oil. The sensitive chip does not directly contact the measured medium. This product features a flat diaphragm structure, making it easy to clean and highly reliable. It is suitable for applications in industries such as food and hygiene.
Product Features of piezoresistive silicon pressure sensor:
- Utilizing advanced technology and 316L stainless steel housing, along with materials such as titanium and Hastelloy for the diaphragm
- Employing thick-film circuits for temperature compensation and zero-point correction
- outstanding reliability, repeatability, and stability
- Flush diaphragm structure, which makes it easy to clean
Applications of piezoresistive silicon pressure sensor: - Suitable for measuring non-corrosive gas and liquid pressure with 316L stainless steel compatibility
- Food and beverage industry
- Industrial process control
- Pharmaceutical industry
Electrical performance of piezoresistive silicon pressure sensor: - Power Supply: ≤2mA DC (Typical 1.5mA DC)
- Input Impedance : 2.5KΩ~6KΩ
- Output Impedance: 2.5KΩ~6KΩ
- Electrical Connection: Gold-plated Kovar pins or 100mm high-temperature wires.

1. Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the
required airtightness
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.
