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

This board-mount pressure sensor provides compact, board-level measurement of small differential pressures in liquid media for integration into electronic systems. It is designed for direct PCB mounting with surface-mount terminals and communicates via standard digital interfaces, enabling straightforward connection to microcontrollers in applications that require precise low-pressure monitoring across a narrow positive and negative range.

• Silicon housing resists chemical exposure for liquid measurements
• Differential sensing covers both positive and negative pressures
• SPI output ensures high-speed digital data transfer
• ±0.25% accuracy delivers precision for control loops
• Operates on 3.3V supply for low-voltage systems
• Withstands temperatures to 110 °C for harsh environments

• Suitable for flow monitoring in medical fluid systems
• Ideal for small-scale hydraulic leakage detection
• Used with microcontrollers in laboratory instrumentation
• Can be used for liquid level sensing in process lines
• Suitable for compact industrial control modules

It measures low differential pressures from -0.072 psi to 0.072 psi, enabling detection of slight positive or negative pressure differences in liquid systems.

The device supports I2C and SPI bus interfaces and provides a dedicated SPI-format digital output for sampled pressure data.

It features surface-mount technology terminals for direct soldering onto a PCB, facilitating automated assembly and board-level integration.

The sensor is rated to operate down to -40 °C and up to 110 °C, accommodating a wide thermal range encountered in industrial settings.
