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
