Introduction of differential diffused silicon pressure sensor:
HT20V is The sensor consists of a silicon diaphragm with piezoresistive elements diffused into it, forming a Wheatstone bridge circuit. When differential pressure is applied across the diaphragm, it causes the diaphragm to deform. This deformation changes the resistance of the piezoresistive elements, unbalancing the Wheatstone bridge. The resulting voltage output is proportional to the differential pressure applied.
Product Features of differential diffused silicon pressure sensor:
1. High Accuracy: Provides precise differential pressure measurements.
2. Excellent Stability: Maintains performance over long periods.
3.Wide Measurement Range: Capable of measuring small to large differential pressures.
4. Temperature Compensation: Ensures accurate readings across a wide temperature range.
- Process Control: Monitoring and controlling pressure differences in industrial processes.
- HVAC Systems: Measuring air pressure differences for efficient system operation.
- Flow Measurement: Used in conjunction with flow elements like orifice plates to measure fluid flow.
- Filter Monitoring: Detecting pressure drops across filters to indicate clogging.
- Level Measurement: Measuring the level of liquids in tanks by detecting the pressure difference between the liquid level and a reference point.
- Power Supply: ≤10VDC
- Common Mode Voltage Output: 50% of the input (typical)
- Input Impedance:4KΩ~20KΩ
- Output Impedance:2.5KΩ~6KΩ
- Electrical Connection:100mm high-temperature wire.

| Ordering tips |
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.
