HT-IQ Piezoresistive Silicon Pressure Sensor
Introduction of flush silicon pressure sensor:
HT - IQ pressure sensor is a flush diffusion silicon diaphragm
pressure sensor. Clamp pressure sensor with disposable silicone oil
filling technology. The pressure felt by the diaphragm is
transmitted to the pressure chip through the silicone oil, and the
compensation circuit corrects the pressure signal to a linear
electrical signal. Clamp mask is pressed directly to prevent
scaling, unsanitary and sticking. Widely used in food, medicine,
alcohol and other health industries and generally suitable for
measuring media may be contaminated occasions. Flat diaphragm with
clamping structure, easy to install and remove, easy to clean.
Product Features of flush silicon pressure sensor:- Advanced technology and 316L stainless steel housing packaging
- Temperature compensation and zero point correction through thick
film
- circuit Outstanding reliability, repeatability, and stability
- High-temperature flush diaphragm structure for easy cleaning
Electrical performance of flush 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.
