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:
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.

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.
