HT Sensor HT-IQT-B Diffused Silicon Pressure Sensor for High Temperature Measurement
HT-IQT-B Piezoresistive Silicon Pressure Sensor
Introduction of diffused silicon pressure sensor:
HT - IQT - B silicon pressure sensor is a kind of embedded diaphragm.Pressure was transferred to the sensitive chip through a stainless steel diaphragm and sealed silicone oil. The sensor chip converts the pressure into a detectable millivolt electrical signal. Thus, we can intuitively observe the pressure value of the measured medium. This product adopts plate diaphragm structure, with high temperature heat sink, high temperature medium measurement effect is good. The bare flat diaphragm is easy to clean and has a good effect on the measurement of viscous media.Apply to food, health and other industries.
Electrical performance of diffused silicon pressure sensor:
- Power Supply: ≤2mA DC (0.4-1.5mA DC).
- Input Impedance : 2.5KΩ~6KΩ.
- Output Impedance: 2.5KΩ~6KΩ.
- Electrical Connection: Gold-plated Kovar pins or 100mm high-temperature wires.

| Ordering tips |
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.
