HT19 Silicon Piezoresistive Pressure Sensor
Introduction:
HT19 is a high-performance silicon piezoresistive pressure sensor, engineered with a core featuring a highly stable diffused silicon sensing element. It operates by transferring the pressure of the measured medium to the silicon diaphragm via an isolation diaphragm and silicone oil, ensuring accurate and reliable measurement of both liquid and gas pressures. Its versatile design and robust construction enable extensive application across demanding environments, including air compressors and refrigeration systems, where consistent and precise pressure monitoring is essential for operational efficiency and safety.
Product Features:
1. The sensor employs advanced manufacturing technology and features a durable 316L stainless steel housing. It also offers optional high-performance diaphragm materials, including titanium and Hastelloy, to ensure superior corrosion resistance and long-term reliability in demanding environments.
2. To enhance measurement accuracy, a thick-film circuit is integrated for precise temperature compensation and zero-point calibration, minimizing drift and ensuring consistent performance across varying operating conditions.
3. With excellent reliability, repeatability, and long-term stability, the sensor is designed to deliver dependable performance in critical applications, reducing maintenance needs and operational downtime.
Applications:
1. Suitable for measuring non-corrosive gas and liquid pressure with 316L stainless steel compatibility
2. Applied in various industrial process sites, including petroleum, chemical, metallurgy, power, and hydrology
3. Used in marine and aviation industries
4. Suitable for hydraulic and pneumatic control systems
5. Utilized in process control applications
Electrical performance:
1. Power Supply: ≤2mA DC (Typical 1.5mA DC)
2. Input Impedance:3KΩ~6KΩ
3. Output Impedance:2.5KΩ~6KΩ
4. 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.
