HTsensor Transmitter core unit flat diaphragm pressure sensor
HT-IQ Silicon Piezoresistive Pressure Sensor
Introduction:
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:- 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:- 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:- 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.
