How Aircraft Pressure Sensors Work: Ensuring Safety from Takeoff to Landing？
Modern aircraft are marvels of engineering, relying on thousands of sensors to operate safely. Among these, pressure sensors play a pivotal role—monitoring everything from cabin air pressure to hydraulic systems. In this guide, we’ll break down the three main types of aircraft pressure sensors, their critical applications, and how they collectively keep flights safe and efficient. 1. Absolute Pressure Sensors: The Altitude Experts How They WorkAbsolute pressure sensors measure pressure relative to a perfect vacuum (0 psi reference). This vacuum-based design makes them immune to atmospheric changes, crucial for altitude-dependent systems. Key Applications Technical Edge: Temperature range: -55°C to 150°C (matches stratospheric conditions). DO-160G certified for vibration resistance up to 20g. 2. Gauge Pressure Sensors: Masters of Relative Measurement How They WorkGauge sensors measure pressure relative to ambient atmospheric pressure. Their sensitivity to environmental changes makes th
