HT19 Diffusion Silicon Pressure Sensor Cell for pressure transmitter
HT19 Silicon Pressure Sensor
Introduction of silicon pressure sensor:
HT19 piezoresistive silicon pressure sensor, the main component is a high stability diffuse silicon sensing element. The sensing package utilizes silicone oil to transfer pressure from a 316L stainless steel diaphragm to the sensing element. Piezoresistive pressure sensor adopts international advanced silicon pressure chip with high stability and high precision, adopts sintering base with optimized stress design, and is produced by SMT, gold wire bonding, diaphragm welding, high vacuum oiling, pressure cycle stress relief, high temperature aging, temperature compensation and other processes.

Dimension
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.
