BP9325-I2C Industrial Pressure Sensor With Stainless Steel Material For Durability
BP9325-I2C Industrial Pressure Sensor with Stainless Steel Material for Durability
BP9325-I2C Silicon Piezoresistive Pressure Sensor
Product Introduction of industrial pressure sensor
The BP9325-I2C pressure sensor adopts our self-developed HT series silicon piezoresistive isolation membrane oil-filled core as the signal measurement element. The signal processing circuit is located inside the stainless steel housing, converting the sensor signal to a standard IIC output signal. The product has undergone rigorous testing and aging screening for components, semi-finished products, and finished products, ensuring stable and reliable performance.

Communication Protocol
BP-I2C uses the I2C bus protocol for communication with external devices. All data communication starts from MSB, with the default 7-bit I2C device address being 0x78. BP-IIC acts as an I2C slave device, and the master device can communicate with it using the following command formats::
When BP-I2C is set to digital output (using I2C 0xAC command), B[23:0] will be output in three bytes respectively. Users can easily convert to percentage using the following formula::
When using the 0xAC I2C command to read out the calibrated 5-byte data, the temperature information is provided by the last two bytes of 16-bit data. Users can easily convert the T value to actual temperature using the following formula:
Note: The bridge default is 10%~90%, the sensor bridge zero point corresponds to 10%, the full point corresponds to 90%. The sensor default does not output temperature values. Temperature output requires customization.
