Product Description
BP9325 Silicon Piezoresistive Pressure Sensor
Introduction:
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:
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:
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:
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
