BP9325 Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
The BP9325 silicon piezoresistive pressure sensor is a highly
stable sensor that utilizes a diffused silicon element. The sensor
measures the differential pressure of the medium by transmitting it
to the silicon diaphragm through a 316L isolation diaphragm and
silicone oil. The diffused silicon element utilizes the
piezoresistive effect to accurately measure the pressure of both
liquids and gases. This design ensures precise and reliable
pressure measurement, making it a popular choice for various
applications.It offers high sensitivity and low power consumption,
making it energy-efficient and perfect for battery-operated
devices.
Product Features of silicon pressure sensor:
1. Utilizes advanced technology and 316L stainless steel casing,
with materials
2. such as full titanium and Hastelloy diaphragm
3. Employs thick-film circuits for temperature compensation and
zero-point correction
4. High reliability, repeatability, and stability
Applications of silicon pressure sensor:
1. Suitable for measuring the pressure of non-corrosive gases and
liquids with 316L stainless steel
2. Hydraulic and pneumatic control systems
3. Process control
