Pressure Sensors Transducers Procurement Notes

Verify the specific pressure type requirement, as this model denotes absolute pressure. Confirm that the unamplified 100 mV output aligns with the system's signal acquisition capabilities. Ensure the panel mount form factor fits the mechanical design constraints. Check compatibility with the required excitation voltage and current limits for the host circuitry.

Pressure Sensors Transducers Selection Notes

Select this component when absolute pressure measurement is required in harsh industrial environments. The 316L stainless steel construction ensures durability against corrosion. The wide operating temperature range supports applications with significant thermal variations. Consider the need for external amplification due to the low-level analog output signal.

Pressure Sensors Transducers Part Context

This part belongs to the NPI-19 series of industrial pressure transducers. The series combines silicon integrated processes with isolated diaphragm technology. The sensing chip is encapsulated in an oil-filled cavity, isolating it from the measured medium via the stainless steel housing.
