Product Description
HT19 Silicon Piezoresistive Pressure Sensor is a high-accuracy industrial pressure sensor engineered for reliable measurement of liquid and gas pressure. Its core is a highly stable diffused silicon element that transfers the pressure of the measured medium to the silicon diaphragm through an isolation diaphragm and silicon oil, delivering precise, repeatable results in demanding industrial environments.
The HT19 silicon piezoresistive pressure sensor measures the pressure of liquids and gases by transmitting the pressure of the tested medium to the silicon diaphragm via an isolation diaphragm and silicon oil. Its versatility makes it widely used in air compressors and refrigeration systems, as well as in industrial process measurement and control.
- Advanced technology with a 316L stainless steel housing; titanium and Hastelloy diaphragm materials available.
- 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.

- 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 the 316L housing material, 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.
