Baoji Hengtong HT26V Pressure Sensor Cell for Transmitter Pressure Sensor Core
The HT26V is a silicon piezoresistive pressure sensor featuring a highly stable diffused silicon element core. The differential pressure of the measured medium is transmitted to the silicon diaphragm through a 316L isolation diaphragm and sealed silicon oil. Utilizing the piezoresistive effect of diffused silicon, it accurately measures the pressure of liquids and gases. The sensor includes an O-ring for pressure sealing, ensuring easy installation.

Parameters tested under constant voltage of 10V and ambient temperature of 25ºC
1. Ensure proper fit between core size and transmitter housing during assembly to achieve required airtightness
2. During housing assembly, maintain vertical alignment and apply even pressure to avoid jamming or damaging the compensation plate
3. Provide special instructions when ordering if the measured medium is not compatible with the core diaphragm and housing material (316L)
4. Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage from deformation or piercing
5. Keep the pressure port of the gauge pressure core open to atmosphere and prevent entry of water, water vapor, or corrosive media into the core negative pressure chamber
6. For any changes to pin leads, refer to the label on the actual core for proper connection
