Product Description
The HT19F is a piezoresistive silicon pressure sensor built around a highly stable diffused silicon element. It measures the pressure of liquids and gases by transmitting the pressure of the tested medium to the silicon diaphragm through an isolation diaphragm and silicon oil. Its versatility makes it widely used in air compressors and refrigeration systems.
- Advanced manufacturing technology with a 316L stainless steel housing, plus titanium and Hastelloy options for the diaphragm.
- Thick-film circuits for temperature compensation and zero-point correction.
- Outstanding reliability, repeatability, and long-term stability.
- Measurement of non-corrosive gas and liquid pressure compatible with 316L stainless steel.
- Industrial process sites including petroleum, chemical, metallurgy, power, and hydrology.
- Marine and aviation industries.
- Hydraulic and pneumatic control systems.
- Process control applications.
- Power Supply: ≤2mA DC (typical 1.5mA DC)
- Input Impedance: 3KΩ~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 vertical alignment and apply even pressure to avoid jamming or damaging the compensation plate.
- If the measured medium is not compatible with the core diaphragm and housing material (316L), provide special instructions when placing the order.
- Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage 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.
