BP9325 Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor transmitter:
BP9325 silicon piezoresistive pressure sensor is a highly stable
diffused silicon element. The differential pressure of the measured medium is
transmitted to the silicon diaphragm through a 316L isolation diaphragm and
silicone oil. By utilizing the piezoresistive effect of the diffused silicon, it
achieves the purpose of measuring the pressure of liquids and gases
Product Features of silicon pressure sensor transmitter:
- 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
- 5. High reliability, repeatability, and stability
Applications of silicon pressure sensor transmitter:
- 1. Suitable for measuring the pressure of non-corrosive gases and
liquids with 316L stainless steel
- 2. Applied in industrial on-site processes such as petroleum,
chemical, metallurgy, power generation, and hydrology
- 3. Used in the marine and aviation industries
- 4. Hydraulic and pneumatic control systems
- 5. Process control
Basic Condition of silicon pressure sensor transmitter:
- 1. Power Supply: ≤2mADC (typical value 1.5mADC)
- 2. Input Impedance: 2.5KΩ~6KΩ
- 3. Output Impedance:2.5KΩ~6KΩ
- 4. Electrical Connection: Gold-plated Kovar pins or 100mm
high-temperature wires
