Pressure Sensors Transducers Procurement Notes

Verify that the specific part number matches the required pressure range and port configuration. Confirm RoHS compliance status if environmental regulations apply to the assembly. Ensure the manufacturing date code aligns with project timelines, as lead times may vary. Cross-reference the datasheet specifications against system requirements before finalizing procurement orders.

Pressure Sensors Transducers Selection Notes

Select this component when a low-pressure gauge measurement is required in a compact form factor. The 1 PSI working pressure suits applications involving gentle airflow or low-pressure differentials. The amplified analog output simplifies interface design compared to raw piezoresistive sensors. Consider the 14-SOIC package constraints for PCB layout and thermal management during selection.

Pressure Sensors Transducers Part Context

This sensor belongs to the NPA-500 series, which utilizes MEMS technology for pressure detection. The series offers various pressure ranges and port configurations to suit different industrial and medical needs.
