Overview

The NPA-700B-005D is a surface-mountable differential pressure sensor providing 14-bit digital output via an I2C interface. Designed by Amphenol Advanced Sensors, it features a dual barbed port for 3mm tubing and is factory calibrated and temperature compensated for high reliability in pneumatic and HVAC applications.

Why Choose This Part

This sensor offers a high-resolution 14-bit digital output which eliminates the need for external ADC circuitry while ensuring a 1.5 percent accuracy across the operating range. The integrated temperature compensation and surface-mount SOIC14 package simplify board-level integration in space-constrained designs.

Applications

HVAC Pressure Monitoring
Precise measurement of air flow and filter pressure drops in environmental control systems.
Medical Ventilation
Monitoring differential pressure in respiratory devices and anesthesia machines.
Industrial Pneumatics
Measuring pressure differentials in automated factory equipment and leak detection systems.

Getting Started

Interface the sensor to a microcontroller via the I2C bus using a 4.75V to 5.25V supply and pull-up resistors on the SDA and SCL lines. Read the 14-bit pressure data and optional temperature data directly from the registers, applying the transfer function specified in the NovaSensor NPA datasheet to convert digital counts to PSI.
