HT20 Differential Silicon Pressure Sensor With Consumption For Industrial Applications

HT20 Differential Pressure Sensor

Introduction of differential silicon pressure sensor:

The HT20 differntial silicon pressure senor is a silicon piezoresistive differential pressure sensor with a core of highly stable diffused silicon element. The core is enclosed in a 316L stainless steel housing, and the pressure is transmitted through a stainless steel diaphragm and sealed silicon oil to the sensitive chip. The sensitive chip does not directly contact the measured medium, forming a fully solid-state structure for pressure measurement, enabling precise measurement of differential pressure. Therefore, this product can be applied in various scenarios that require differential pressure measurement, including harsh and corrosive environments
Product Features of differential silicon pressure sensor:

Stable and reliable performance
High resistance to static pressure
Cost-effective
Utilizes silicon piezoresistive oil-filled pressure-sensitive element

Applications of differential silicon pressure sensor:

Differential pressure detectiony
Pressure calibration instruments
Liquid level measurement
Industrial process control

Selection Examples

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.
