Hydraulic and Pneumatic Control Systems with BP9325 Silicon
Piezoresistive Pressure Sensor
BP9325 Silicon Piezoresistive Pressure Sensor
Introduction of silicon industrial 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 industrial 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 industrial pressure sensor:

NOTE.:
1. During assembly, pay attention to the fit between the size of
the sensing element and the transmitter housing to achieve the
required air-tightness.
2. During assembly, ensure the sensor is aligned vertically and
press it down evenly to prevent jamming or damaging the
compensation plate.
3. The measured medium must be compatible with the material of the
sensing element diaphragm and casing (316L). If not, special
instructions should be provided when placing an order.
4. Do not use sharp objects to press the sensor diaphragm, as it
may cause deformation or puncture of the diaphragm and damage the
sensing element.
5. The pressure sensor's vent tube must be kept open to the
atmosphere.
6. If there are changes in the pin leads, follow the label carried
by the sensing element for accuracy.
