HT19 Piezoresistive Silicon Pressure Sensor
Introduction of 15mm silicon pressure sensor:
HT19 piezoresistive silicon pressure sensor, the main component is high stability diffuse reflection silicon sensing element. The sensing package utilizes silicone oil to transfer pressure from a 316L stainless steel diaphragm to the sensing element. The piezoresistive effect method of diffused silicon was used to measure the gas and liquid pressure. It is the most commonly used diffused silicon sensor to measure pressure, and the price is cheaper than other types.

| Ordering tips |
1. Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the required air tightness
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.
