Pressure Sensors Transducers Procurement Notes

Verify the specific suffix (e.g., -T006) against your system requirements, as ordering codes may indicate tape-and-reel packaging or specific calibration variants. Confirm that the 0–20 PSIA range aligns with your maximum expected pressure inputs. Ensure the SPI protocol compatibility matches your microcontroller or avionics processor before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this component when precise absolute pressure measurement is required in space-constrained aerospace environments. The 24-bit resolution supports detailed air data computation. Verify that the 4–12 V operating voltage fits your power distribution architecture. Consider the -40°C to +85°C operational range against your mission profile thermal constraints.
