Overview

The BPS120-AD0P30-2DG is a high-precision, ultra-low pressure differential sensor designed by Bourns for sensing clean, dry air and non-corrosive gases. It provides a 13-bit digital I2C output and is calibrated to measure differential pressures up to 0.3 PSI (2.07 kPa) with high accuracy across its operating temperature range.

Why Choose This Part

This sensor offers a high Total Error Band (TEB) accuracy of +/-0.25 percent, ensuring reliable data for critical low-pressure applications. Its surface-mount J-Lead package and I2C interface simplify integration into modern digital control systems while maintaining a small PCB footprint.

Applications

HVAC Filter Monitoring
Detecting pressure drops across air filters to determine when maintenance or replacement is required.
Ventilators and Respirators
Precise monitoring of low-pressure air flow in medical breathing assistance devices.
Industrial Process Control
Measuring small pressure differentials in pneumatic systems or cleanroom environments.
Environmental Monitoring
Monitoring air quality and flow rates in HVAC ducting or sensitive laboratory equipment.

Getting Started

To integrate this sensor, connect the SCL and SDA pins to your microcontroller I2C bus with appropriate pull-up resistors and provide a supply voltage between 2.7V and 5.5V. Use a standard I2C library to read the 13-bit digital output and apply the transfer function specified in the Bourns BPS120 datasheet to convert raw counts into PSI or kPa.
