BP9325 Stainless Steel Housing Piezoresistive Diffused Silicon Pressure Sensor Industrial
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.
