Product Description
The HT24 is a flush diaphragm pressure sensor core built around a highly stable diffused silicon piezoresistive chip. Pressure is transmitted to the sensitive chip through a stainless steel diaphragm and sealed silicon oil, so the chip never comes into direct contact with the measured medium. Its flat diaphragm structure makes the sensor easy to clean and highly reliable, making it well suited to food, hygiene, and other demanding industrial environments.
- Advanced manufacturing technology with a 316L stainless steel housing; diaphragm available in 316L stainless steel, titanium, or Hastelloy.
- Thick-film circuits provide temperature compensation and zero-point correction.
- Outstanding reliability, repeatability, and long-term stability.
- Flush diaphragm structure for easy cleaning and hygienic operation.
- Measurement of non-corrosive gas and liquid pressure compatible with 316L stainless steel.
- Food and beverage industry.
- Industrial process control.
- Pharmaceutical industry.
- 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

- Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the required airtightness.
- During housing assembly, ensure the core is aligned vertically and apply even pressure to avoid jamming or damaging the compensation plate.
- If the measured medium is not compatible with the core diaphragm and the 316L housing material, special instructions should be provided when placing the order.
- Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage to the core from diaphragm deformation or piercing.
- Keep the pressure port of the gauge pressure core open to the atmosphere and prevent water, water vapor, or corrosive media from entering the core negative pressure chamber.
- If there are any changes to the pin leads, follow the label on the actual core for reference.
