NPA-500B-10WD

Pressure Sensors Transducers Overview

The NPA-500B-10WD is a differential pressure sensor from the Amphenol Advanced Sensors (NovaSensor) NPA-700 series. It features an I2C digital output with 14-bit resolution and operates within a supply voltage range of 4.75V to 5.25V. The device provides a full-scale output corresponding to a working pressure of 0.36PSI (2.49kPa), with a maximum pressure rating of 35PSI (241.32kPa). Accuracy is specified at ±1.5%. The component utilizes a 14-SOIC package with a top port configuration, featuring dual 0.12-inch barbed ports for connection. It supports surface mount installation and includes temperature compensation.

Pressure Sensors Transducers Procurement Notes

Verify that the specific suffix 'W' corresponds to the required packaging or variant specifications as defined by the manufacturer's official documentation. Confirm that the I2C address and protocol requirements align with the host microcontroller capabilities. Ensure the operating environment remains within the specified -40°C to 125°C temperature range to maintain the stated ±1.5% accuracy. Cross-reference the pinout diagram with the target PCB layout to ensure correct orientation of the top-port connections.

Pressure Sensors Transducers Selection Notes

Select this component when a digital I2C interface is preferred over analog outputs for direct microcontroller connectivity. The 14-bit resolution offers enhanced precision compared to standard analog variants. The top-port design facilitates easier tubing connection in constrained board layouts. Consider the 0.36PSI working pressure limit to ensure it matches the system's operational range without exceeding the 35PSI maximum burst pressure.

Pressure Sensors Transducers Part Context

This part belongs to the NPA-700 series, which distinguishes itself from the NPA-500 series by offering digital I2C outputs rather than analog voltage signals. While sharing similar physical dimensions and port styles with other NPA modules, the NPA-700B-10WD specifically addresses applications requiring digital signal processing. It complements other models like the NPA-500B-10WG, which provides an analog alternative within the same mechanical footprint.

Pressure Sensors Transducers Replacement Considerations

The NPA-500B-10WG serves as a functional alternative if an analog voltage output is acceptable instead of I2C. For different pressure ranges within the same digital series, consider other NPA-700B variants. Verify compatibility regarding the I2C pull-up resistor requirements and voltage levels before substituting.
