Pressure Sensors Transducers Procurement Notes

Verify the specific suffix A2 confirms I2C digital output and absolute pressure type, as the NPI-19 series includes analog and gauge variants. Confirm the 1/8" NPT port size matches system requirements. Check RoHS compliance status if restricted substances are a constraint. Ensure supply chain availability aligns with project timelines due to standard lead times.

Pressure Sensors Transducers Selection Notes

Select this model when absolute pressure measurement is required rather than gauge or sealed gauge types. The I2C interface suits microcontroller-based designs avoiding analog-to-digital conversion complexity. Consider the 100 PSI range against system operating pressures. The cylindrical package and NPT connection dictate mechanical integration constraints within the target assembly.

Pressure Sensors Transducers Part Context

Part of the NPI-19 series rugged industrial pressure sensors. Designed for harsh environments with stainless steel housing. Offers both analog millivolt and digital I2C options. Targets applications demanding high reliability and accuracy in automotive, aerospace, and industrial sectors.

Pressure Sensors Transducers Replacement Considerations

NPI-19J-100G2 offers similar 100 PSI range but uses analog output. NPI-19A-100A2 provides digital I2C output but differs in packaging or port configuration. Verify mechanical fit and electrical interface compatibility before substitution.
