How to Choose the Right Aerospace Pressure Sensor: Key Criteria for Engineers？
Selecting a pressure sensor for aerospace applications isn’t like picking a smartphone case. One wrong choice could mean fuel leaks, system failures, or even safety risks at 35,000 feet. But with so many specs and certifications, how do engineers and procurement teams cut through the noise? Let’s break it down using real-world aviation logic. 1. Pressure Range: Know Your Altitude Extremes Pressure sensors must handle everything from ground-level takeoff to near-vacuum cruising altitudes. Why it matters: Airbus A350s use sensors with 0.1–100 psi ranges to cover all flight phases. 2. Accuracy vs. Precision: Don’t Mix Them Up Aircraft fuel systems demand both: 4. Output Signals: Speak Your System’s Language Match the sensor’s output to your avionics: Case Study: Boeing’s 787 Dreamliner uses ARINC 429-compatible sensors for seamless avionics integration. 5. Weight Math: Grams Add Up A single sensor’s weight seems trivial – until you multiply it across 30
