Honeywell Technologies ABP2 Series Board Mount Pressure Sensor, Analog Output -0.072 psi, Differential Reading 0.072 psi

This board-mount pressure sensor provides precise differential pressure monitoring for liquid media on printed circuit assemblies. It integrates a silicon housing and an SMT terminal for compact surface mounting, and communicates via common digital interfaces while also offering an analogue signal for straightforward integration into measurement systems. The device is designed for operation across a broad temperature range and low-pressure detection scenarios.

• ±0.25% accuracy enables high-precision pressure measurement
• 0.072psi maximum span permits detection of very small pressure changes
• I2C and SPI interfaces allow flexible digital system integration
• Analogue output simplifies legacy or mixed-signal readouts
• 3.3V maximum supply supports low-voltage systems
• -40 to 110°C operating range suits harsh thermal environments

• Suitable for medical liquid flow monitoring systems
• Used with laboratory equipment for microfluidic pressure control
• Ideal for HVAC condensate and drain-line monitoring
• Can be used for industrial lubrication system sensing
• Used for environmental chambers requiring low-pressure detection

It employs an SMT terminal designed for automatic pick-and-place and reflow-solder processes.

The sensor is specified for liquid media and calibrated for differential liquid pressure applications.

The supply voltage must not exceed 3.3V and must remain above -0.3V to avoid overstress.

With an approved operating window from -40 to 110°C it can be located near heat sources or within cold enclosures while maintaining specified accuracy.
