NPA-730B-030G

Pressure Sensors Transducers Overview

The NPA-730B-030G is a sealed gauge pressure sensor from the NPA-730 series, manufactured by Amphenol Advanced Sensors. It features a 14-bit digital I2C output and operates within a supply voltage range of 3.135V to 3.465V. The device has a working pressure of 30PSI (206.84kPa) with a maximum pressure rating of 60PSI (413.69kPa). It utilizes a 14-SOIC package with top dual ports measuring 0.12 inches (3mm). Accuracy is specified at ±1.5%, and it includes temperature compensation for operation between -40°C and 125°C.

Pressure Sensors Transducers Feature Summary

• Integrates a MEMS pressure sensing element with an ASIC for digital signal processing.
• Provides calibrated and temperature-compensated digital output via standard I2C interface.
• Features a compact surface-mount SOIC package with integrated barbed ports for tubing connection.

Pressure Sensors Transducers Applications

• Medical gas delivery systems
• Respiratory therapy equipment
• Infusion pump monitoring

Pressure Sensors Transducers Procurement Notes

Verify that the specific suffix '030G' corresponds to the required 30PSI sealed gauge range and I2C communication protocol. Confirm the 14-SOIC package dimensions and pinout compatibility with the target PCB layout. Ensure the operating environment remains within the specified -40°C to 125°C temperature range to maintain accuracy specifications.

Pressure Sensors Transducers Selection Notes

Select this component when a digital I2C interface is preferred over analog outputs for noise immunity and simplified microcontroller integration. Choose the 30PSI range if the application involves pressures up to 206.84kPa. Consider the sealed gauge configuration for applications referencing atmospheric pressure rather than absolute vacuum or differential measurements.

Pressure Sensors Transducers Part Context

This part belongs to the NPA-730 family of board-mount pressure sensors designed for healthcare and industrial applications. Unlike the NPA-700 series which typically uses 5V logic, the NPA-730 series is optimized for lower voltage operation around 3.3V. The 'B' in the model number indicates the sealed gauge pressure type, distinguishing it from absolute ('A') or differential ('N') variants within the same series.
